Dry mouth from Wellbutrin and lithium and Provigil. I eat everything, everywhere, all the time. On my current regimen, this seems to be due to lithium, a medication that has been associated with appetite issues. I developed a movement disorder on Abilify, which we d/c'd as a result. The movement disorder is almost completely gone now, thankfully. I, of course, also have a lithium tremor. And right now, short-term, I am on Zyprexa and it makes me super-tired during the day.
