Unfortunately, I fall into the not so lucky group of people. I was on 20mg of Lexapro and actually just switched to Prozac.
I definitely gained weight ... and a LOT of it.
Don't get me wrong, it did really help with my anxiety, but it's hard not to be anxious when you can't lose weight and just gain it!
Hope your experience is better than mine!
Plus, if you only think about the anxiety relief, then it's a pretty good pill.
Hopefully Prozac will be better for me!
