"so far it is working, very well.  it is curbing my desire to reach for more than one portion at a time. it is allowing me to eat less and think twice about what i am consuming.  the fatigue is present,  but you have to consider the drop in food intake and the medication. i am doing the atkins diet, taking supplements and exercising when i am able too. headaches disappeared after the first day.  definitely worth it for me.  print out the coupon it will help to offset the expense of the medication."
