"i am on bupropion sr for 2.5 months and it&#039;s been pretty good so far. i don&#039;t sleep all the time like on citalopram and my weight stayed the same with a slightly diminished appetite. the depression is mostly gone even though i&#039;m unemployed for a long time living off dwindling savings. but i&#039;m actually trying to get work now since i have more energy and feel generally better than ever despite the economy. my libido isn&#039;t much despite other comments here. 
some anxiety still there and a few drinks in the evening help that.
the biggest side effect is extreme sweating when it is humid and above 70 degrees. it&#039;s embarrassing.
for me, bupropion (wellbutrin sr) 100mg twice a day mostly works. good luck."
