Hi all. I am hoping for a response on this site because I have posted here before with great results. Here goes. I took Lexapro for years and really experienced no problems. About 6 months ago, because of insurance reasons, I had to switch to Citlapram, sorry I know its misspelled. After always feeling tired and hungry, my doctor switched me to generic prozac 5 days ago. I had no problems until today, when I was driving and my stomach hurt bad to the point of diarrea, misspelled again. Anyway, I got pretty anxious. I was wondering if I am just now having a reaction to the med change, like a withdrawal or something, or a case of the stomach flu. I think the anxiety was maybe from being in the middle of nowhere and not getting sick. I came home and took a nap and feel ok, but, as usual, I am very worried. Can anyone help me out here?? I was also taking an antibotic for something unreleated, and was wondering if that was a player too. It is notrious for stomach problems. Anyway, any help to ease my mind would be great. Thanks.
