I've been having stomach problems pretty much every day for the past year with symptoms such as nausea and reflux. After several visits to different doctors and doing all kinds of testing they couldn't find any medical fault so I finally accepted the fact that the problems resided in my head 3 months ago. I talked to my doctor and we came to the conclusion that I suffered from severe anxiety. How and why I've been struck by it I don't know. Possibly because I had a little too much to do on my table. In order to cure this my doctor prescribed SSRI (http://en.wikipedia.org/wiki/Citalopram) and I've been eating them now for 2 months and I'm starting to feel better. I've also begun going to a counselor to talk about my problems.
