depression
"Have taken other medications in the past and stopped due to the side effects.  Now I take bupropion xl 300 mg a day with no apparent side effects.  I can laugh.  I can still cry.  I don't dwell on bad things.  It makes me just feel better.  But Dr accidently wrote for SR once.  I went ahead and took a dose (thinking it would be basically the same, only a little faster acting - I took a 150 mg dose) and was sick as a dog and felt drugged.  Amazing the difference in XL and SR - and I imagine the fast acting would be even more severe.  I'll stick to the XL."
