I'm currently on Paxil at 40mg headed to 60mg in another week. I do ok on it I guess. I'm not feeling any better yet but maybe the entire cocktail together will help. I haven't suffered any side effects from Paxil and have been on it before. I experienced the same thing with cymbalta. I was taking 60mg and vomiting everytime I took it.
I haven't had any trouble with weight gain from Paxil ever but I know some people say that is a side effect for them.

Hope you find something that works for you soon.
