I don't know if any of you have been put on Lexapro yet. It's the newest antidepressant out there. I just wanted to let you know my experience with it. My doctor assured me that I would not gain any weight on this one....however, this has been the one I gained the most weight on in a very short time. It also made me feel horrible...very irritable. I am now in the process of weaning off. Just thought I'd share this with you.
