depression
"I started Wellbutron about 1 year ago.  I have primarily taken 300mg daily.  A while back we tried going up to 450mg, but my tremor was too bad so we decreased the dose to 300mg.  A couple of weeks ago we tried going up again, but had to stop because of the tremor and also I was having tremendous memory difficulties.  Half way through a sentence, I couldn't remember what I was talking about.  I had poor word-finding abilities, and twice in one day I couldn't remember what street I was driving on and how the streets met up at intersections.  I also went to a movie with a friend and though I remember going to the movie, I have no idea what it was about.  Back down to 300mg, I am much better, but still experiencing lesser symptoms."
