Wellbutrin made me restless, manicky, and I just generally "didn't feel right," although it didn't make me delusional in the way that SSRIs do. Antidepressants just make things worse for me.
However, I've heard Wellbutrin has helped a lot of people with Bipolar, along with a mood stabilizer at the same time. Meds are tricky and how they vary from person to person.
