Hi and welcome to SR
I've been on Wellbutrin (Bupropion) since the end of August. If i may suggest, wait it out. Give it a solid 3 months before switching. My dr. told me that many times people switch too quickly.
It is also perscribed for weight loss in heavy people and that's why you have no appetite also to quit smoking. I specifically am on it for depression but my weight issue is part of my depression so it's nice not to feel hungry all the time. The only side effects that i really had/have is at night, sometimes my mind races and it's hard to fall asleep. My. dr. suggested a sleeping pill (low dose) to help.
I will tell you that i had anxiety and alot of symptoms because i was reading about the side effects and it became like i took on the side effects. At first, I thought for sure i would have to get off it but now i LOVE it and wouldn't change for the world. I'm on 200 mg twice a day.
But like others have said, if this one is not to your liking, see your dr. about switching, there are millions out there. I was on Prozac at one point years ago but didn't like that one.
Good luck and i bet you start feeling better soon
