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'm just dropping in to update that I'm still off of caffeine after 22 months and still doing fine. No pains in the back. No more catastrophic thoughts of fatal diseases. I do occasionally have a desire for coffee, but then I remember how painful and scary it was breaking the addiction especially the neuropathy and the psychological aspect.

I have many people amazed that I am now off of caffeine and asked how to do it. SMH. I tell them to just stop, but it took me 8 or 9 months to completely recover. Their jaws practically drops and they dismiss the idea of quitting.

I am still very grateful to be off of caffeine and have every intention of remaining off of it!!! I have the feeling if I remained on caffeine for too much longer then my health would have paid the price.

I wish everyone the best at remaining off of caffeine or getting off of caffeine!!

Has anyone else developed

Has anyone else developed sensitive teeth after coming off caffeine?

And a happy caffeine free year to you too. I've made a promise to my girlfriend on Christmas Eve that I wouldn't drink caffeine for a year, so I guess I have to do it now ! So far so good....

Tummy Pain

I'm new to this site. Been drinking caffeinated beverages for about 10 years and I recently quit about a month ago. I had headaches for about a week and then that went away. Now I have this burning like pain in my abdomen for about five weeks. Can that be a withdrawal symptom? How long does it take to go away? I have read a few people's post but haven't seen much replies.
