depression
"I've been taking 300 mg of Wellbutrin for two months now, and I am really impressed with how great it has been.  I am way more motivated, feel happier, and quit smoking too.  I find it much easier to go to work, and going to the gym is actually wonderful, instead of the incredibly difficult task it was before.  I think that Wellbutrin works particularly well when combined with exercise.  I have had a little bit of dry mouth and some trouble sleeping, but when compared to the benefits, the side effects are very minor."
