depression
"Took 50 mg in the morning as directed, the day went fine and I was productive but was awake all night.  Didn't sleep at all and felt jumpy for the first hour or so out of bed.  I've been on Wellbutrin for years and felt like it might not be helping anymore -- well, after a scary night where I felt like I was on a bad trip -- just make it stop -- I'm back to Wellbutrin.  If anyone knows a good alternative to Wellbutrin that's not Effexor or Pristiq, I'd love to hear about it."
