I am considering starting prozac for the third time. The past two times I was on it were around 14 years ago so I've been med free for a good while. Both times it worked very well for me but the first two weeks were horrific. I felt a zillion times worse. I have recently tried citalopram but straight away it gave me sexual side effects and most of the stuff I read online seemed to suggest that this is something that doesn't really get better. I never had this with prozac. I was wondering whether those who have been on it more than once or multiple times could tell me whether you had similar side effects each time and whether it worked as well for you.
