depression
"I'm on my 5th day of Bupropion for generalized anxiety and depression and so far very happy.  Appetite is way down (food drive was through the roof before) and although sex drive has not changed, the degree of pleasure is up.  I had a feeling of lightheadedness for the first two days before it subsided.  The only real side effect is a mild case of localized dystonia at the base of my neck.  I have had such a positive experience so far with the drug (compared to the many side effects of other medications) that I think I can live with a little discomfort and rigidity for now. "
