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.

10 months and Counting

This is my 10th month Caffeine free and I must say I feel amazing. This whole withdrawal thing has been quite a crazy experience!! I went through it all (severe panic attacks, dizziness, severe fatigue, body feeling like a lead weight, digestive problems, sleeplessness ,etc). At times it was pure hell!! So for all those who are just starting the journey, hang in there! It's all worth it when you make it to the other side.

How long did it take you to

How long did it take you to really come out of it and feel the way you do now?

Re: How long did it take you?

It took a good three months to get over the worst of it and another two to three months to feel completely normal. Each person is different. Also I did the cold turkey method, so the weaning off process may be better for some people. This message board was a blessing during my withdrawals. It was a huge help:)

Wow...Well now I know what

Wow...Well now I know what I'm up against. I quit for a month once but still felt tired and crappy. Thought it was just me. Even went to the doctor and had tests run but everything came back normal. Mentioned my caffeine use but the Doc sort of brushed it off. I'm sure he's a an addict too like about 80% of everyone else. Thanks for responding.

hi im 24 years old and i

hi im 24 years old and i havent had coffee in 7 days b/c i thought maybe i had fibromyalgia. During these 7 days without coffee i cant sleep, my legs and arms feel restless, im having lower, mid and neck pain along with alot of my joints, im having mood swings, headaches, im often crying at time, during nights i cant sleep or having panic attacks. I was wondering if all this is caused by no caffeine. After wat i was reading about alot of ppl goin through this, that maybe it could be the caffeine and not fibromyalgia

Could be that you've also

Could be that you've also dramatically cut back on your water consumption - heavy coffee drinking, whilst hammering your system with caffine, also provides a steady flow of water.

If you haven't replaced your missing drinking with something new this could be causing your other symptoms.

I've replaced my coffee with Red Bush tea - caffine free, something to drink when I get that craving. I'm tired, cranky and having trouble focussing on anything - but it's working. 4 days and counting :S

caffine withdrawals

I am now at day 5 caffine free. I drank up to 2 cans of coca cola a day for the past 4years. I am on 3weeks holidays so I figure now is a good time to quit. Over the past few days I've lacked motivation, been irratable, have felt fatigued and fuzzy in the head. Yesterday was my worst day. I had hot flushes ,felt sick and muscle aches and pains. I thought I was coming down with the flew. I am determined to get through this as I know it will make me healthier in the long run and I don't want my body to be a slave to addictive substances.

Caffine withdrawl

If you taper your caffine consumption over a couple of days, you can quit with only a mild headache if any!

Kicking Caffeine is Hell!!

I'm a 23 year old female. I have LOVED Mt. Dew and sweet tea since I was old enough to drink it. I never realized how much the caffeine affected my life. When I was 17 I was diagnosed with IBS (Irritable Bowel Syndrome). My doctors told me to stop drinking all caffeine and have no chocolate. I quit caffeine cold turkey-no problem. Eventually, I started drinking sweet tea again because I realized it didn't hurt my stomach like coffee or sodas did.
Now I'm trying to get healthy. I joined a gym and have been working out regularly. I have also been adjusting my diet. The next thing I'm trying to eliminate is caffeine. In the past month or two I have tried multiple times to quit caffeine but I always give up because by noon or earlier, I have a horrible headache. I have a job where I stare at a computer all day long and this extreme headache just makes it absolutely horrific.
However, today is my second day without caffeine. I have an awful headache and I can't even focus on my work (hence why I am browsing the Internet). I get migraines and have had hangovers but this headache is so much more than either of those. I really don't know how I will manage to get through this weekend or next week at work... Hopefully I can continue drinking the water and working out. Maybe that will help the symptoms... :(

You can do it,

I was wondering how you did on kicking the caffeine. It is hard with the terrible headaches but they really do only last 3-5 days at the most. I have the worst affects of caffeine withdrawal. One tip I'll give you is that once you've kicked it, don't have anything with caffeine again because if you are truly a caffeine addict, all it takes is once glass of mountain dew or a cup of coffee to start it all over again! Believe me I know, I'm back in a bad phase of drinking it again but I think you've motivated me to quit again and stay with it!!!
(sad that it sounds like an alcoholic talking but its very similiar in what it does to you!)
