Cinder,

I am on Wellbutrin XL, and the only side effect I had was that I got these terrible nightmares, but they went away after about two months. I did not have any weight gain...in fact I have lost weight.

I would make sure you bring up all of the side effects with your pdoc...Wellbutrin can be a great med, but there are some potentially serious side effects, so you need to be completely up front about what your experiencing.
