Wellbutrin XL and wellbutrin xl

so far i took it for about two months. Yes it's an anti-depressant aid, but I was prescribed this medication to help with my smoking habits. I felt a surge of energy, and a concentration to do things, but I've also noticed that it keeps me awake. It's similar to insomnia. It's not that I can't sleep, but that I don't want to. I know that if I just lay down and go to sleep I most likely will. But other than that, I don't believe it has helped me quit smoking. It, I guess, made me feel happy? I really don't think it worked...
