"i have gone from 160 lbs to 135 lbs (25 lbs lost) in 3 months while taking this medicine. it is awesome. i am also tracking my calories and trying to stay at 1000calories/day.  it is very important to see your doctor regularly and be monitored while on this medicine.  my doctor will only prescribe this for 3-4 months.  i am being told there are studies for long-term usage.  i am nervous to go off of this medicine because it works so well.  i am able to manage portion control, eat healthy, increase exercise and not want to eat after dinner.  this medicine was the answer to my many years of struggling with my weight.  i wish i could stay on it forever but i can&#039;t.  i think about food all day long except for when i am on this medicine."
