What are the symptoms of caffeine withdrawal?

Regular caffeine consumption reduces sensitivity to caffeine. When caffeine intake is reduced, the body becomes oversensitive to adenosine. In response to this oversensitiveness, blood pressure drops dramatically, causing an excess of blood in the head (though not necessarily on the brain), leading to a headache.

This headache, well known among coffee drinkers, usually lasts from one to five days, and can be alleviated with analgesics such as aspirin. It is also alleviated with caffeine intake (in fact several analgesics contain caffeine dosages).

Often, people who are reducing caffeine intake report being irritable, unable to work, nervous, restless, and feeling sleepy, as well as having a headache. In extreme cases, nausea and vomiting has also been reported.

The past 10 days have been pretty good. I did wake up one morning with a slight panic feeling, but I was able to disconnect my thoughts from going negative and had faith that this is just part of the caffeine withdrawal process. I went to the gym for a really hard workout to successfully rid myself of that feeling.

I have a friend expressing an interest in also quitting his caffeine addiction. He's a truck driver, so he said that he can't imagine being able to quit. I suggested exactly keeping track of his caffeine intake and very gradually over weeks or months decreasing his consumption of caffeine until he was caffeine free. However, people often speak of giving up addictions, but rarely follow through.


I like how Mandy describes one of her caffeine withdrawal symptoms as "diagnosing self with all kinds of catastrophic diseases". I still struggle with this even though not as frequently as before. Each time I have physical symptoms occur, my mind starts analyzing it and fears the worse case scenario. Considering caffeine is a psychoactive drug, I find it fascinating that coming off of caffeine 129 days later can still have me thinking like this. I can see why the medical community can't make the connection. I can't make the connection and only believe it because I am experiencing it along with others on here. It's hard to understand why the "diagnosing self" symptom happens during the withdrawal period and not while I was actually consuming caffeine. I'm not asking anyone to explain it. I'm just sharing my thoughts.

The neuropathy that I experience has lessened over the past month. But, when the neuropathy increases for a day or two, I begin to worry about the possibility that it's MS. I know that the neuropathy didn't start until I stopped caffeine and later diagnosed with Vitamin D deficiency, so logically the odds of coincidentally having a two issues (Vitamin D deficiency and MS) that share the same symptoms must be very very remote. The only thing that seems to explain the "diagnosing self with catastrophic diseases" is that the depression that I felt in the 1st 60 days is still present on a much lower level under the surface and this depression distorts my perceptions. I'm probably overthinking it, but this is what is on my mind on day 129.

Along with MS, I've begun to worry about congestive heart failure. Pressure in the lower part of my calf has me worrying that I have fluid retention. I've only begun to worry about my heart in the past couple of days. I exercise 2 to 3 hours almost everyday, so it's crazy for me to think this. Plus, other than this weird filling, there is no evidence that it is fluid retention. I press on the skin of my calf and the color resumes to normal quickly. I just keep reminding myself that this "diagnosing self with catastrophic diseases" is part of my caffeine recovery process.

Reading about what others go through on this website helps so much. I appreciate everyone's contribution.

Think less....

I really think you need to think less. I appreciate that hypochondria is probably a recognised psychological disorder, but you've got to think the constant stress of imagined diseases will probably end up making you ill !! Live in the day, be thankful you're fit and well now.


I realize that overthinking is counterproductive. For the most part, I'm winning this battle. I just have lapses. However, the point of me posting was just to share what was going on in my mind at this stage of caffeine withdrawal for other people to read in the future. Some people might go through the same thing and reading that I went through the same thing might give them some hope and encouragement. While I appreciate your offer of solutions, I not really asking for solutions. I know that I just need to wait it all out.


...and I was acknowledging Mandy's comment that "diagnosing self with catastrophic illnesses" is a symptom. I know this because it is a symptom that I have.

Mandy it is good news, it

Mandy it is good news, it makes me feel envious and hopeful at the same time. I am 18 months off and can't wait to be able to say that I am feeling really really good.

At the moment I would say that I have recovered by about 45% on the fatigue (it fluctuates still, but 45% is on a good day)
My mood (depending on the amount of stress life throws at me) is about 55% improved. The weird burning and other strange sensations in my feet have completely stopped although they do still feel a tiny bit numb, and I still occasionally get cramps in my legs but not my feet any more. I still get back ache, but that has also improved by about 50%, and I still get the shakes and I am still clumsy, all improved by about 45%.

Insomnia is about 45% improved, and my gut problems are about 50% improved. The woman who wrote "Welcome to the Dance" said that she still had fatigue at 2 years and 3 months off, but most of the other symptoms had stopped.

I am a bit confused by your last remarks about your insomnia, I think there must be a few typos there, and I would like to know how your improvement went regarding insomnia, if you have the time to post it.

Oh and I still have itchy eyes a lot of the time too.

I expect I have forgotten something, but that's all for now. I hope you go on feeling better and better as other people have reported. I also share your feelings about my friends when I see them knocking their huge coffees back, but its a waste of time going on about it, especially as I can't tell them that I feel wonderful for coming off it, YET!!!!!!!

eight months free and clear

eight months free and clear and finally i am feeling good, sometimes i think ive not felt as well in years, its such a relief, good luck to evryone else, from my point of view its well worth quitting and i was terrified by the withdrawal i experienced diagnosing myself with all kinds of catastrophic illnesses in addition to loads of strange mini syptoms like phobias, twitchy muscles and mild allergic reactions, lt was also six months out of my life and im picking up the pieces now, my friends, my hobbies, i had only been manging the bare minimum at work, but its all coming back now. phew its over. i know how hard it is, i am proud even in awe of myself for getting through it and you will too. best wishes.


.......and Mandy, strangely only recently have I started having the twitchy muscles that you mentioned. Seems odd that it waited until now to start! I'm hoping it's a good sign.


Hello Mandy. That is awesome to hear. Congrats!! I'm so happy for you. And, I'm happy to hear a number like six months when you finally made it past the withdrawal period. Gives me something to shoot for. However, I feel like I've made a lot of progress the past week. It sounds like many people share similar withdrawal symptoms while at the same time many of the same people have their own unique symptoms and challenges to overcome.

The first number I shot for was 60 days. It seemed to be quite the milestone. Now I'm marking 180 days as my next milestone. And since you're at 8 months, it sounds like you've been doing great for the past 2 months. Am I understanding you correctly? Great job!! And thanks for coming back and sharing.

hi and thank you for sending

hi and thank you for sending me congrats, it is important to come back and share progress i think mostly because when i felt at my worst i was on here all the time getting the reassurance i needed, ive read every single message, several times, and the relief i felt when i recognised the similarities with others. i am sounding a bit OTT perhaps but it was a tough time. so yeah i felt i had come through it at six months but its only for the last two or three weeks that ive felt good, good enough to recognise feeling good, and i still have the mildest versions of the symtoms but they are so mild now i only just notice, like the funny head swimmy feelings that were always one of the worst for me. it was years of diet coke for me, two litres a day, for 17 years ish - i went out to lunch with five friends today and four of them had coke with their lunch and i wanted to say: its a drug!!! its changing your brain chemistry, you must be addicted at some level to even think you enjoy it, its noxious chemical gas and poison ! but i didnt say any of that. am just glad yo be free. if it helps i had: panic attacks, headaches, insomnia, weird head feelings that scared me no end, trembling, anxiety stuff like derealisation depersonalisation, twitching muscles, stiff muscles, little phobic things like eating food with a napkin held round having thoughts of contamination and dizziness with major light headedness and weird glycemic things getting anxious about must eat while not being hungry because of these things i developed a thought that i would collapse, and it all came on within a couple of hours of quitting, major intensity and then week by week it lessened, but some symptoms were like a acute surge so the insomnis lasted as bout five weeks at the three month mark, and now hardly anything.....bit of funny head stuff yeah but hardly, its worth it worth it worth it
