depression
"I am on bupropion SR for 2.5 months and it's been pretty good so far. I don'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'm unemployed for a long time living off dwindling savings. But I'm actually trying to get work now since I have more energy and feel generally better than ever despite the economy. My libido isn'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's embarrassing.
For me, bupropion (Wellbutrin SR) 100mg twice a day mostly works. Good luck."
