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.

caffine is a drug

caffine is a drug and it can actualy block the pain reseperters in your brain. I used to drink coffee because i had races in the morning at like 4 AM. I quit now and have been free for 3 weeks. i still am not feeling clear yet and my sleep pattern is all messed up. Right now, i am just a mess and it is going to take some time for my brain to recover. I kinda feel like a meth adict in a way. So, good luck to you all.


Well I had the most important exam session last week and had been drinking 2 cups of relatively strong coffee (300-400 mg i guess) Today I only drank a small cup of espresso - cutting it down slowly. IT is evening here and in this very moment I'm feeling quite fatigued and have this weird pain in my back and in my knees. I'm gonna try to stop coffee altogether since my bowels burn and i get heartburn sometimes as well. I also dislike the whole idea of being dependent of some substance.
How long to be at 100% again? I've been drinking 1-2 cups a day for 4 months now with 1 week pauses.

Curious, did you take the CFA

Curious, did you take the CFA exam? I just took it as well on Saturday.

cfa addiction

I took the cfa exam, now I'm on day 4 sans coffee. I had to up my dose to get through studying. I've so far been able to manage the symptoms with lots of water, excercise, and ibuprofen. I was drinking maybe 5 cups per day.

How to help the leg pain

I'm on day 4 (or 6, depending on how you count - I'll explain in a bit) and into my 3rd day of serious leg pain. I mean screaming, can't-focus-on-anything-else, difficult-to-walk pain. How do you alleviate this symptom?!? I have a desk job so I thought maybe the lack of exercise was making it last longer than "average". So last night I walked for 45 minutes - my legs still woke me up at 4:30 this morning and I think they are worse, if anything. I'm drinking water like a fiend. Never been big into over-the-counter medication so I haven't taken aspirin or alleve or anything.

Something has to help. I've even found myself wondering if I need to go back to the bean just to make it stop. The only thing keeping me on the wagon at this point is I don't know if/how fast that would help. I know all about the headache and exactly how much coffee it takes to make that go away but the leg pain... WIMPER.

My waffling on the days is because I chose to quit cold-turkey in the middle of suffering one of the worst stomach bugs of my life (school age kids - gotta love em). Regular coffee intake on Friday (about 24 oz, regular brew, every morning for the last 6 years), vomitting Friday night, didn't get out of bed or have coffee on Saturday (I certainly had a headache that day but bug or withdrawal, who can say?), tried to "normalize" on Sunday but only managed to choke down a few sips of coffee and that is when it finally occured to my illness-ridden brain that this is my opportunity to quit the bean. So I'm on day 6 if you ignore the Sunday sips or day 4 if you count them.

Pluses of this "detox method" is that I definitely feel like I skated through the headache dept - was suffering anyway and since I so rarely can spend a whole day in bed, I feel like I really managed that well. But the leg thing took me totally by surprise and I am not happy! Make it go away!

Caffeine-induced muscular pain - ibupofen

Persevere! Try a nonsteroidal antiinflammatory (NSAIDs) like ibuprofen or aspirin (but don't take on an empty stomach as it will irritate the stomach lining). You'll see results and start to feel fine by day8...HONEST!

I went cold turkey; was expecting a headache at the start, but this did not materlialise to the extent I imagined and there was no craving for coffee. Day 2 foggy-headed, depressed and listless and very tearful. Day 3-4 arms and legs like lead weights, irritable, unable to concentrate on anything, a complete 'can't be bothered/cannot muster any energy for work' attitude and intense cramping of thighs, glutteal muscles (buttocks) and lower back - couldn't sit, stand, walk or sleep - AGONY. Pain releaved by popping ibuprofen 2x day. Day 8 and the pain has disappeared, the world is back in glorious technicolour and my senses and memory have been sharpened 1000-fold. So please hang on in there. It will take about 14 days for everything to re-adjust itself; this is the time taken for adenosine receptor downregulation in the brain to take place, in the absense of caffeine, and for the adrenal glands to start producing the correct level of adenosine to circulate in the blood. Caffeine blocks the adenosine receptors, meaning that the adrenals have to works extra hard to secete a sufficient amount of adenosine. Once the caffeine disappears, there is too much adenosine circulating in the blood. This affects the blood vessels causing them to constrict and this is what you feel as pain in your muslces. Blood vessels constrict, oxygen cannot be transported to muscles (and lactic acid and carbon dioxide excreted) and you get muscle spams and stiffness and that awful wont-go-away caffeine PAIN. Eventually, things are normalised and the adrenals recover and start to produce the correct level of adenosine and you start to feel normal. Your adrenals are no longer overworked and you have more energy WITHOUT the coffee.
Make sure you have enough sleep during the 'cold turkey' period mind.... all part of the self-healing process. And don't get despondent. Remember there are countless other pour souls around the globe who are going through exactly the same as you are. You'll succeed. Good luck :o)

I think I've made it. Day 11

I think I've made it. Day 11 (or 13) and I no longer have any of the leg pain from my previous post. I was still getting twitches but could tell it was improving by day 9 or so. And I did end up taking ibuprofen for 2 nights (around day 6 and 7) in order to be able to sleep. But now I miss it! Not the taste or the "ceremony" of it - just the pick-me-up. Into the mental stage of withdrawal, I guess. I'm tired - just dragging and could fall asleep just about anytime, anywhere. Sleeping 7 to 9 hours a night and the 7 hours feels like not nearly enough. I am better on 9 hours but really, who has 9 hours to devote to sleep?!? The leg pain experience is now helping me though - anything whose withdrawal can be that painful canNOT be good for you! I don't care how many anti-oxidants it has or how many studies says it helps prevent Parkinsons and colon cancer. I'll get my antioxidants from a non-addictive source, than you very much!
Thanks for the support and listening - it also helps!

Hi, I gave up coffee ( &

Hi, I gave up coffee ( & other unhealthy foods) 9 days ago & have had a constant headache ever since. Does anyone know if this is normal?
I read headaches can be expected for 1-5 days. Thanks.

Day 9 and getting better (slowly !)

I've battled with caffeine addiction for many years - when I drank it I felt groggy, unfocussed and anxious yet every morning I'd start again as the withdrawal was so unpleasant. I felt totally trapped. I kept trying to taper off - by drinking tea rather than coffee, by measuring a specific dose of caffeine in pill form and replacing coffee with this, reducing slowly each day and so on. Generally I'd last a couple of days then stop tapering and go back to mainlining coffee. I spent a fortune on supplements and vitamins to help me detox and feel better, made 'rules' about how much I could drink etc. None of this worked and I was slowly driving myself crazy being trapped in the addiction.

I finally quit 9 days ago cold turkey. I had a bit of a revelation and thought "screw it" - I'm just going to stop. No taper, no supplements, no hocus pocus. Just take it a day at a time and deal with whatever comes my way. It hasn't been easy, but it hasn't been as hard as I thought it would be - as with so many things in life, the fear of doing it is far greater than the reality. A couple of things I did do that seem to have helped have been sleeping when I needed to - the first 2 days I slept for an hour in the middle of the day, something I wouldn't normally do. I also made sure I drank A LOT of water in the first 4-5 days. I would think 10-12 pints each day. Sounds a lot, but I just made sure I drank around a pint each hour I was awake. I went to the bathroom often, but my withdrawal symptoms were far less than I imagined, maybe the water helped flush my system ?

The withdrawal symptoms I got were tiredness and inability to focus, just feeling I was dragging around, low grade constant headache and significant muscle tension and pain. I felt my leg and back muscles all the time, constantly tense and sometimes painful. One night I had to take painkillers to give enough relief to allow me to sleep.

Now after 9 days it's getting better. I've slept better than I have in a long time and have really focussed on getting re-hydrated. My thinking and focus is clearer, I'm saving money and overall life looks better. I'm still not fully out of the woods - my back is still a little tense, my legs still twitch a bit and I still have a mild headache but it's much better than it was. I've heard it takes a couple of weeks for the symptoms to have gone, and then a couple of months to fully recover your health.

I'm looking forward to the journey. Still taking it a day at a time, but so happy to be free from that pit of addiction. I've quit smoking and drinking in the past and found both easier to stop than caffeine. It's one serious drug !

You can do it!!! I was a

You can do it!!! I was a serious caffeine diet soda drinker for about 25 years. I quit cold turkey and it was awful. I thought I was going crazy. Once the headaches were over, my muscles hurt. I was nauseous. Milk helped. I also took 1 multivitamin every day. Drank some sprite too. After that passed, I suddenly got panic attacks which i had never experienced. I was restless at night, and thought I would lose my mind. Whenever I felt that way, I would focus on doing an activity, or watching a tv show to occupy my thoughts. I went on some walks, but would feel lightheaded.
So I only tell you this so if you have these symptoms you will not be alarmed. You are not severely ill nor are you going crazy. I haven't had caffeine for 2 years now. I can honestly say it took about 1 year to be completely rid of the drug, and it is a drug. I feel great now. I sleep better. I wake up WAY more easily, and am not addicted to anything.
You can do it. Do it for your long-term health. Every time you feel terrible, think about how great it will feel to not be an addict. After my experience kicking caffeine, I have empathy for those trying to kick illegal drugs. All drugs are a serious problem that mess with your body chemistry.
You will make it, just stick with it. Be strong.
I did it! You can too!
