Caffeine is the most universally consumed stimulant of the central nervous system. It works primarily as an adenosine antagonist. Adenosine itself works as an inhibitory neurotransmitter that helps suppress activity in the central nervous system. Since caffeine is an antagonist for the adenosine receptors, it tends to speed up nervous system activity in a dose-related manner.
As a natural consequence of blocking the adenosine receptors, it can also influence the effects of other major neurotransmitters including acetylcholine, serotonin, and norepinephrine. It also has a smaller influence on cortisol, epinephrine, and glutamate production. It has been shown to improve learning, memory, coordination, and overall cognitive performance. Most people consume caffeine to help them fully wake up and feel stimulated before the work day.
However, not everyone likes relying on a drug to help them get through the day. Although caffeine is one of the safest ways to “perk up” in the morning, some note that it can lead to long term dependency. For this reason, many people prefer to withdraw and take on life naturally – without the influence of drugs.
Factors that influence caffeine withdrawal include:
1. Individual physiology
Various physiological factors may impact your ability to withdraw from caffeine. For example someone that is naturally more mentally aroused may have an easier time withdrawing from caffeine than someone who is naturally underaroused. Additionally some people may not notice any withdrawal symptoms whereas others may notice many.
2. Frequency of use
How often do you drink caffeine can play a big role in determining the severity of your withdrawal. Do you drink caffeine on a daily basis? Do you drink it multiple times a day? Do you drink it all day every day? Obviously the more times you use caffeine throughout the day, the tougher it will be to withdraw from.
3. Amount of caffeine you drink
Caffeine amounts typically range from 16 mg to 160 mg. Coffee typically has about 135 mg of caffeine, whereas an energy drink may have up to 160 mg. Various types of tea typically have between 15 mg and 40 mg of caffeine. If you are pounding energy drinks on a daily basis, your body has likely become accustomed to high levels of caffeine.
This will make withdrawal more difficult as opposed to someone who only drinks white tea daily. In fact the person drinking white tea may not even note any withdrawal symptoms.
Believe it or not, some people actually become dependent on caffeine for everyday functioning. Although it is a safe substance, the fact is that people use it for a mental crutch. It improves cognitive function and acts as a mental stimulant. Most people also notice improvement in energy levels and mood following ingestion of caffeine.
If you are dependent on caffeine for functioning in the workplace and/or it has become a staple towards helping you stay productive, withdrawal may be pretty difficult.
Common Caffeine Withdrawal Symptoms
Below are just some of the symptoms that you may experience while withdrawing from caffeine. Not everyone is going to experience all of these symptoms. You may only have a minor headache and feel a little sluggish before you bounce back to 100%. However, others may have a variety of symptoms that may make life difficult to deal with for a couple of weeks.
- Anxiety: Although anxiety can be a response to drinking too much caffeine, some people can feel anxious while withdrawing. This has to do with the fact that the caffeine may have perked up their brain in social and performance-based situations. Now that they are coming off of the caffeine they feel anxious because they are not at the same level of performance as they were with caffeine.
- Cravings: Many people experience cravings for caffeine. Although the addiction and abuse potential is low, some people have a difficult time kicking their coffee habit. It is common for you to physically and psychologically crave caffeine for a couple weeks into withdrawal. The craving alone should show you how certain people can become dependent on this substance for functioning.
- Constipation: Since caffeine tends to stimulate bowel activity and movements, withdrawal may result in constipation. This tends to last a few days at the maximum and will eventually subside. Try to stay active and eat healthy to encourage normal bowels.
- Depression: Since caffeine can produce a mood boost for some people, a natural consequence of withdrawal is a mild depression. You likely aren’t going to feel severely depressed, but you may notice that you feel sluggish, moody, and don’t feel like doing anything – this is normal and will subside.
- Diarrhea: Some people note that they experience diarrhea when stopping caffeine – this is less common than constipation, but can be annoying to deal with.
- Dizziness: It is common to feel somewhat dizzy when withdrawing from the consistent ingestion of high amounts of caffeine.
- Flu-like symptoms: Some people report headaches, muscle pain, as well as vomiting. Obviously these can be minimized with gradual tapering of caffeine as opposed to “cold turkey” quitting. Typically only people that have become extremely dependent on caffeine will exhibit flu like symptoms.
- Grogginess: Anyone that drinks caffeine can experience a “crash” and feel groggy. This will eventually go away as your body and brain recalibrate to life without caffeine.
- Headache: Some people report standard headaches for the first few days of withdrawal, while others report experiencing migraines. This is your brain undergoing an adjustment – eventually this will go away. In the meantime take some Tylenol and wait a few days – the headaches will subside.
- Insomnia: Although it is more likely that you will experience insomnia if you drink caffeine too close to bedtime, some people actually experience insomnia during withdrawal. I know this is counterintuitive, but withdrawing affects everyone differently.
- Irritability: If caffeine gave you a slight mood boost or subtle feelings of happiness or perk, it is common to be irritable when withdrawing.
- Lack of motivation: If you relied on caffeine to provide you with motivation, it’s going to be difficult getting through a few days or weeks in which you have zero motivation.
- Lethargy: Most people end up feeling vey lethargic for a few days after quitting the use of caffeine. Some would say that this feeling is like a minor hangover.
- Mood swings: Some people experience minor mood swings during their withdrawal period.
- Muscle rigidity: You may notice that your muscles become tense and/or rigid. Again, this is another counterintuitive response that people have reported.
- Nervousness: If caffeine helped perk you up to function in social situations, you may feel nervous as a result of slowed cognitive function.
- Poor concentration: The inability to concentrate is very common. Caffeine is well known to enhance cognitive functioning so stopping it can negatively affect cognitive performance.
- Shakiness: Some people get the shakes or feel shaky when stopping.
- Sleepiness: The tiredness and sleepiness may be difficult to cope with, but it will eventually subside.
- Slow thinking: Since caffeine acts as a stimulant and speeds up brain activity and functioning, not using it can result in slowed thinking. Eventually your brain will recover to its natural, homeostatic state. Fortunately the slow thinking here isn’t typically as severe as it would be during an Adderall crash.
- Sluggish: It is very common to feel like a total slug for a few days when quitting caffeine.
- Sweating: Some people may experience light sweats or even sweat profusely as their body gets reacclimated to functioning without caffeine.
Note: After ceasing ingestion, the caffeine stays in your system for around 1.15 days after your last dose. As a result, some people notice most symptoms emerge within 1-3 days of stopping.
How long do caffeine withdrawal symptoms last? Timeline can vary.
Most people suggest that the brunt of the physical symptoms such as bad headaches and constipation will go away within the first 48 hours of withdrawal. In other words, once a couple days have passed since you’ve ingested your last dose of caffeine, most of the physical symptoms should subside. However, if you were a chronic caffeine drinker, it is certainly plausible that they would last longer. In general, withdrawal for most people lasts between 7 and 14 days to fully recover.
It should be noted though that any substance that your body becomes dependent upon for everyday functioning may have an even longer withdrawal. There are cases of people experiencing withdrawal symptoms well after 2 weeks. Much of how severe your withdrawal will be depends on your individual physiology as well as other psychosocial factors. It also depends on whether you withdrew “cold turkey” or with a standard tapering method (e.g. gradually weaning off of it).
Although it may seem as though you are going crazy during withdrawal, you’re not. Caffeine withdrawal is extremely common. It may be an unpleasant experience, but it typically isn’t nearly as severe as other drugs or withdrawal from alcohol. Caffeine has a relatively low abuse potential and is considered a pretty safe substance. While you withdraw from caffeine, plan a few days to overcome the major symptoms such as on a weekend or vacation break so that most of them are not plaguing you the following week at work.

Remind me again why we drink coffee? I should say drink. After a 15 year abstinence from coffee, I drink it again to utilize the theophylline in order to combat an acute histamine reaction. Worked very well. Then, I had a reaction to the caffeine after withdrawing suddenly.
Symptoms included intense pain in sinus passages, nostrils almost completely blocked, feeling of tickling sensation in the back of throat and in Upper chest, sleeplessness, then oversleeping, some dizziness, some exertional dyspnea, difficulty concentrating.
Swollen fauces, I may add. This is now day 5. Thus, the adage about withdrawal being prolonged through prolonged caffeine consumption seems to be, perhaps only in my case- or not, pure myth.
The key to reducing severity of withdrawal seems to lie in reduction of caffeine by around about 1/4 to 1/8 of a cup every 3 days until caffeine is reduced to practically zero.
Good luck everyone! From your friendly Insomniac, former medical officer in special forces, Nicholas.
I have been cutting my daily caffeine consumption in half for 7 days. I had mild headaches for the first few days, but my worst symptom has been insomnia. 2 nights this week I did not sleep at all – not a single minute – and still had to go to work the next day.
I’ve never had sleeping problems before this. Other nights I’m getting about 5 hours of sleep with the help of sleeping aids. I don’t know if anyone else has experienced this. This is one of the only articles I found that listed insomnia as a withdrawal symptom. It has been the hardest thing for me.
I stopped drinking too much coffee a year ago. I only drink one small cup on one day a week, most weeks during my school year. I am seventeen years old and started drinking coffee when I was seven. Now I drink mostly herbal tea but have caffeine teas only when I absolutely need it.
I don’t drink much soda, but when I do, I avoid sodas with caffeine. If I go a long enough time without caffeine, and then have it after that long period of time, I get nausea, lightheadedness, fatigue, and hand shakiness. Almost like anxiety symptoms but not. I have GAD and I can tell the difference between the two… Am I just very sensitive to caffeine?
I don’t normally comment on posts BUT 1 week ago I cut out coffee cold turkey after 16 years. I drank about 6-10 MUGS of coffee a day. I made in my coffee pot about 12-18 cups a day (yes, I was a bad caffeine addict). I had IBS and constantly had stomach issues (severe gas, bloating, un-normal bowl habits).
I had reached my limit on not being able to figure out what was bothering me – doctor after doctor. The stress of eating was really getting to me because I didn’t know what was going to bother me. I’m 5’3″ and 110 lbs and 5 out of 7 days a week I looked 6 months pregnant. I was at my wits end.
I came across a post that said caffeine/coffee was the worst thing for digestion issues. So I decided to give it one last fair shot and quit this addiction of 16 years. My story:
-Day 1: This isn’t hard whatsoever! Slight headache and lethargic but nothing intolerable.
-Day 2: Stomach was NOT bloated, I was feeling mentally positive. Withdraws really kicked in! Massive headache and constantly tired, felt for about 17 hours of the day. Nap after nap after nap.
-Day 3: Just kill me… insanely hurtful headache, body aches, nauseous/vomiting & chills/shaking.
slept again for the majority of the day
-Day 4: Headache not as bad and not sick to my stomach anymore. My lower back/joints hurts which made it hard to sit still. Took some Advil to ease that pain
-Day 5: Faint headache but compared to the last 4 days, nothing I can’t easily deal with – still a little tired.
-Day 6: Headache gone, more in tune with my body, my hunger, my feelings, got more energy and overall felt SO MUCH BETTER.
-Day 7: ALL my symptoms were gone and I felt GREAT.
Overall: The withdraws are very hard and physically painful. At times I said I can’t do this and wanted to go make coffee. I didn’t though b/c I was so far into it that I didn’t want to go back. BUT in the end, SO worth it!
My stomach for 7 weeks straight now has NOT been bloated what so ever! I have not had 1 bit of bloating, not 1 gas pain, no stomach pains/cramps. It was incredible & a miracle. I have more energy, I sleep better and longer at night & my mood has overall just been relaxed & my anxiety has decreased significantly.
I love how thoroughly meticulous you are in your record-keeping. That is an important step in withdrawal. I hope things are going very well for you now.
I decided to give up caffeine about two weeks ago. I started trying decaffeinated coffee but after a week I decided to not drink coffee at all. I started to have pain radiating down the back of my legs, headaches, my heart rate increased and blood pressure spiked.
My blood pressure has gone down but I use to run a little under the normal blood pressure. I keep tabs on it daily. I am going to do a 21 day detox. I am hoping and praying all goes well. In Christ Jesus name.
I forgot to indicate I drank a about 3 to 4 cups of expresso a day (Starbucks venti).
I used to drink coffee for about 7 years and then switched to black tea (one strong cup in the morning) for about 12 years. Last month, I decided to try to get off of tea completely; I knew I was addicted. The first few days, I had the terrible headache, but Tylenol helped.
About 2 weeks later, I had horrible pain in the back of my thighs for several days (I was afraid it was a blood clot), but this pain also went away with Tylenol. I noticed that if I drank decaf tea or ate about 4 pieces of chocolate, the headaches came back.
It was almost as though I had re-started the withdrawal process (return of headaches) by introducing a small amount of caffeine. These headaches resemble migraines; the back of my right eyeball is usually the source of the pain. Also, most recently, my eyes are becoming very sensitive to light, leading to pain, so I started wearing sunglasses indoors.
(I usually never had headaches or sensitivity to light, even without sunglasses). I am wondering if anyone else has experienced these residual withdrawal symptoms after the initial withdrawal headaches, and how long the eye sensitivity lasts or if it becomes permanent.
This caffeine withdrawal process has been a bit scary, I really don’t want to do it all over again by going back to drinking the tea… unless my health requires it.
I’ve been drinking 2 large cups of coffee with real Baileys every morning for 15 years. It is my luxury in life. Got my first UTI (urinary tract infection) ever. With a little research I realized caffeine makes it worse. So, I decided not to have coffee the next morning. In fact, I thought, I’m going to just stop coffee all together. Well, on the first day… around 3pm or so I started getting a slight headache.
Thought about it being withdrawal symptoms since I NEVER get headaches. By 7pm that first night even I couldn’t move my head. My neck hurt so badly, my entire head and then even my cheekbones and teeth hurt so bad I couldn’t put my nightly braces in. And those nightly invisi-line braces I’ve been wearing for a year so there is no movement. But my teeth even hurt so badly.
It was so severe, I said the heck with this… made myself a small cup of coffee at 2030 and drank it down. I would say my headache and neck pain only decreased about 20%. I finally took a prescription pain pill that I had from 2 years ago and went to bed. Unfortunately for me, pain meds keep me awake. After about an hour and a half the pain level was down to about 20% from the 100%. That’s as long as I didn’t move my head at all.
This morning I got up and told my husband everything. He and I have decided to slowly wean ourselves from coffee together. But this morning, I made both of us one cup of large coffee each. We won’t have that second one. We will have one cup for 3 days, then lower it to 3/4 of a cup for 3 days, then 1/2 a cup for 3 days, then 1/4 cup… then maybe a gulp… hahaha!.
Don’t know about anyone else out there contemplating weaning yourself from coffee… but I strongly recommend a slower wean. Unless you can stand excruciating migraines and other major symptoms from detox, there is just no reason to put yourself through that much pain. It really is so bad that as I lay there in bed… it made me realize how people that are on their death beds, reach a point in their life where they just give up and say please let me die.
I’m ready to go. It was real and it is painful. Looking forward to being off coffee and once I am, I will never go back to it again. Many blessings to all of you in your journey to be caffeine free. It’s worth it. Anything that makes your body that addictive to it cannot be good for you. The only people who truly benefit are the coffee companies.
It’s not a real energy drink in the sense that it gives you a false energy and it depletes your natural energy from occurring. You can do it if you really want to.
I got the stomach virus or food poisoning one a week ago today. Well I couldn’t keep anything down for like 18 hours including Pepsi. The next day I had a few drinks of Pepsi but then decided now was a good of time as any to stop drinking Pepsi all together BC my anxiety has been awful and hopefully that will help.
Well yesterday (day 6) was the worst, my anxiety was through the roof and horrible brain fog. Everything seemed like it happened a week ago and it had just happened that morning. Today (day 7) is somewhat better. I also had my labs drawn to make sure it wasn’t and iron or b12 deficiency either.
I’ve been praying that God give me strength and he has. In all my moments of fog get still gives me a few clear moments. Prayers for everyone struggling. I refuse to quit BC I don’t want to be dependent on something to function.
I have been putting it off but alas I’ve heeded the doctor’s advice to stop coffee (all caffeine), alcohol, chocolate, any all foods that are acidic. I’ve been recently diagnosed with a medical condition that necessitates making these changes in order to be pain free and have quality of life. Coffee, wine and food have been a major part of my life and I am 61.
I stopped cold turkey 36 hrs ago and it’s weird I never had a headache but all the other symptoms are debilitating. Feeling listless, depressed, spaced-out and hurting. I drank anywhere from 1-2 cups a day for 30 yrs… that’s it! I’m wondering if all the things at once are exacerbating the symptoms.
I would have 1-2 glasses of wine or beer a night. Occasionally a scotch. I’m on this “elimination diet” to determine which of these drinks/foods trigger my condition. After 4 wks I introduce one at a time, gradually, back into my body to see if my symptoms return. I now know what sacrifice is like, with Lent approaching.
Wow… I am on my 6th day of no coffee. I was having the strangest pain/stiffness in the back of my neck… (where my “neck bone” meets my skull)… hurt so bad to move my head up & down, side to side…
I also feel a bit of the blahs… I miss the spark coffee gave me. After reading all of these comments, I’m wondering if after this 21 detox is done, do I really need to add coffee back? We read so many articles that says coffee is actually good for you, but I don’t know now…
Thanks for providing this place where people can share their experiences. It has been very helpful.
