I take Wellbutrin, along with a mood stabilizer and it didn't cause any increase in anxiety, or make me hypomanic, which for me has been the mixed mood kind, agitated, angry and a bit dark.

I started it several weeks before the mood stabilizer, when I was being treated as if I had only depression and anxiety. While it didn't cause any negative symptoms it also did zero to help with the depression.

That hasn't been my experience with all AD's, lexapro made me really hypomanic and took me to a bad place in my head, although I didn't realize that's what it was at the time.
