Wellbutrin
"I've been taking 150mg for 2 weeks now. I felt the effects in just a few days.  I have a lot of energy, and has increased my thirst. I've lost a few pounds. My only problem is sleep. I've been taking zolpidem for 3 years (5 mgs) and isn't helping much. I've taken a few other antidepressants in the past, and this has been the most effective."
