Hi, I took prozac for 14 years without any bad side effects, it worked great! The only thing was some nausea for a week or so, but not bad. I had to switch to cymbalta because the prozac just quit working after that long of time on it. I wish I could take it again. Cymbalta has side effects, cannot be late in taking it, and you have to wean of it since body becomes dependent on it. Good Luck and donot worry! Sandy
