I'm not on Wellbutrin - But I wanted to try it for a while (I had an eating disorder and couldn't) so I know a bit about it. I know it's a drug for a very "empty" depression. I am anxiety prone during my depressive phases. If your depression comes with a feeling of lethargy, Wellbutrin could do wonders.
It has virtually no side effects (except for an increased chance of a seizure, especially if you have an eating disorder) and is one of the only anti depressants without sexual side effects. There can be a small chance you'll be allergic to it, though that's quite rare.
Overall, a good drug according to what I've heard. :)
