obesity
"I have had no problems with this medication.  I feel extremely alert except at night, which I fall asleep quickly.  I have lost 5 lbs in the first week because I am eating only what I should be eating. I have no appetite for the extra junk I have been eating for the last few years, when I put all this weight on me.  Oh and now that I am not so consumed with my weight and snacking, I can concentrate on work so my work has improved as well."
