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.

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!!!
Thanks!
(sad that it sounds like an alcoholic talking but its very similiar in what it does to you!)

find another way to heal the IBS. just have a cup

Maybe the coffee is causing the IBS! Not worth it. I suffered through overwhelming side effects due to coffee/caffeine addiction. I have been through the withdrawal several times. The improvement in my health is dramatic (each time). Caffeine addiction affects all 24 hours of every day. NO cup of coffee tastes as good as being healthy feels.

caffine is a drug and it can

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.

For the last several years, I

For the last several years, I would wake up every morning with a nasty headache. I had no idea what was causing it, but I knew I needed to do something about it eventually. I put off going to the doctor, because they'd just prescribe pain meds. On a whim, I decided to quit drinking my usual 2 cups of coffee each morning (this was around May 15, 2010), and to abstain from drinking anything but water. The withdrawal was unbelievably horrible! However, the amazing thing was my morning headaches completely went away after about day 3 of drinking nothing but water. Clearly, what was happening is my body was craving those 2 cups of coffee each morning while I was asleep, and the withdrawal headaches were waking me up. It's now been about a month, and I've been completely headache free (not just in the mornings, but throughout the day) for that entire time. I've also noticed tons of other beneficial changes from drinking nothing but water (losing weight, don't have to use the restroom very often at all). I'd be willing to bet at least half of the medical/health problems in America could be solved, if everyone stopped drinking "substances".
