I'm only on Wellbutrin at the moment, and I get dry mouth from it. I make sure I have chewing gum any time I'm going to be talking a lot or exercising, since that seems to help. When my pdoc upped the dosage I had a couple weeks of constant migraines, but they went away.

When I was on Prozac, it made me hear voices. Got off of that one quick! I don't remember side effects for anything else, though - seems my body is generally tolerant.
