depression
"I've been diagnosed and treated 20 years ago for major depression (used Prozac).  Last year I was diagnosed again for major depression and doctor suggested I try Wellbutrin so it would not affect my sexual desire and give me some energy.  I did well the first few weeks on the starter dose 75mg/day. Then they up to 150mg/day and I had a major emotional reaction.  My body went into crying spells for 20 minutes and I couldn't control it.  It was a weird thing. Stopped it immediately - took 2 days to wear off. "
