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.

Caffeine side effects

I have a question - I had a headache after day 1 of quitting caffeine, however for 4 days straight I have had constant pain in my thigh muscles. Has anyone else experienced this? it is very strange. Any help is much appreciated.

Constant pain in my thigh muscles

IMG! Yes, I went off tea (not coffeee) on Monday. It is Thurs and my thighs are still killing me. Fiesrt 2 days was a headache with the thigh aches. Feels like I ran a marathon. I decided to go off off even green tea, because I was addicted to it (I guess that isn't bad). I guess it depends on you level of caffeine tolerance, some people can gussle the stuff all day at Starbucks and I'm dying from weaning off of grean tea. Took Advil for the pain, woke we up at nite with a deep pain in my hips and thighs. Hope that helps!

Yes... I have been "cold

Yes... I have been "cold turkey" for 2 weeks now. I drank a TON of coffee... Starbucks... I mean like at least a pot a day if not more.... I love it and miss it.

My headaches were excruciating....my body aches- almost laughable how the changed each day- but my hamstring muscles ached like I ran a marathon... weird? Why? So yes- your thighs can hurt!

I'm on my 3rd day. Got raging

I'm on my 3rd day. Got raging headaches and woke up this morning with pain on my thighs and butt. Go figure. From reading all I've read here, I guess its normal?

Caffeine Side Effects

I am on day three of a Diet Coke detox - 2-4 liters a day for 10+ years. I can handle the headaches, but the pain in my thighs and legs is distracting. I keep waking up several times a night due to leg ache.

Caffine Withdrawals

You are experiencing the same withdrawal symptons that I have!
I went on the web to see if my symptons were related to going off caffine.
I have headaches and aches in my lower back (kidney area), thighs and legs.
I am glad to read your comments to confirm that the symptons are related to caffine withdrawal.
Actually decaf coffe from Tim Hortons tastes just the same as caffinated coffee and is very good.
That is all I have been drinking for the past four days.
I went off caffine because my doctor said that my stomach problems were do to a Hiadas Hernia.
You know, my stomach has not bothered me to much over the past few days.

Good Luck!

No doubt. I experience this

No doubt. I experience this pain every time I've quit caffeine, although my pain is in the hamstring area (back of my legs). If you search, you'll find that many people complain about this pain. However, after much searching, I can't find what causes it! Kind of scary...


Thank-you thread-writers - its great to see I'm not alone. I've come off coffee twice (four mugs of black coffee a day) and I get a withdrawal similar to mild opiate withdrawal (I work in a detox so I've seen it). Even my doctor didn't believe me and said I just got a flu at the same time. Flu doesn't make your vision go and the muscle aches are terrible - and different from flu and accompanied by cravings - thats not flu and I've had it twice so I should know! Thank-you everybody for sharing your stories, I gave up coffee - my favourite drug - to try and get my energy back, this thread has inspired me to keep clean! It was easier to pack in drinking. By the way my wife has struggled with a one can a day aspartimine addiction, that stuff is definitely addictive and she can't replace the diet coke hit with caffeine so its definitely the aspartimine.
