"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."
