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.

I havent gone off caffeine in

I havent gone off caffeine in years. After I had some panic attacks last year I maybe went off for 2 weeks. I developed anxiety and some depression last year and I think caffeine had a major part in that. At that time I was drinking close to 500mg of caffeine a day!

Anyway I use workout energy supplements (which contain caffeine and other stimulants), but they havent done much for me lately (I hadnt used them in months before trying again recently). So I decided I needed to take a break from stimulants. I thought back to how caffeine used to make me feel super awake and excited and stuff, but now it just like gets me through the day. In the morning if I dont drink any coffee or anything I feel completely drained.

Last week I went 6 days without anything, but then I broke and had coffee/energy drinks for the last 4 days. Now I swore I would start again and go for a full month. I hate this depressing feeling of ZERO energy all day.

I had the headache and I've

I had the headache and I've been taking a ton of naps - all of which I can deal with, but now I'm getting the "flu-like" symptoms and its miserable. The nausea is the worste part. I've been using mass-quantities of water to fend off the other symptoms, but I can't stand water when my stomach is upset, so the cravings are 10 times worse now. I'm on my 7th day and they say you're officially "no longer addicted" on the 9th day. I can't wait for the next two days to be over!

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.
