I took Prozac for a year about 12 years ago, for depression. After my dad passed away I went into a deep depression that wouldn't go away. Prozac worked. Unfortunately, it also had a very nasty side-effect, in that I gained a subsantial amount of weight while on Prozac. Which I managed to lose after getting off it. A few years ago, when I needed an antidepressant again, I was put on Celexa (also an SSRI)... and gained weight again. Now that I am off it, the weight is coming off again...
I do remember my doctor asking me if I noticed any change to my sex drive from the antidepressant. I truthfully told him that there was no change. What I didn't tell him was that since I don't really have a sex drive in the first place, there was nothing to change.
But anyway, I know other people who gained weight while taking an SSRI, so this would be something to watch out for.
