depression
"Wellbutrin XL has so far been a miracle pill for me. I was always in a deep cloud of depression and my mind was always so "foggy" I could never focus or think properly and I was always too depressed to even get off the couch and do a load of laundry. I started on 150mg for a few weeks then moved up to 300mg. 

Now I am loving life again, things that had no appeal before are amazing again. I've also lost a ton of weight while taking this, probably because I'm more active. I also have had some slight constipation (not bad at all only slight at times) not to mention an increased sex drive. It seems I can be in the mood 5 times a day. The wife can't handle all that extra me time. "
