Emma,

Welcome to the forums. I take Wellbutrin for depression, and anxiety is one of the most common side effects of bupropion. Some of the other things you're experiencing may be due to the increased anxiety. I know for depression, doctors will often not prescribe Wellbutrin for people who have anxiety as well, but I'm not sure there's an alternative for smoking cessation.

Not sure if that's much help, but at least you know that the side effects you are experiencing aren't unusual. I'd talk with your doctor to see if there might be some alternatives to try.
