Hi there,
I have been taking 20 mg. Lexapro for over six months now. The wierd thing I've noticed with it is for me at least, it helps me sleep and not be as suicidal, but it doesn't make me happy either. It makes me feel kinda numb and out of it. I don't know exactly how it works or anything, but it like gets rid of a little of the bad, but doesn't replace it with anything?
Anyway, something that might help is combination therapy. I have a friend who takes 10 mg. Lexapro and Wellbutrin. She says that the Lexapro helps ease the bad thoughts, and the Wellbutrin replaces them with happy thoughts. So I guess it works better. I'm working on checking into it myself. I don't know if that sounds good to you, but it might be worth a try?
Good luck
