"after 2 years of very slowly losing pounds to reduce blood pressure,doc prescribed this drug.i reached my half-way weight loss goal(13lbs) after a month taking it daily.i stopped taking it and kept exercising and gained about 4lbs back.doctor advised i keep routine and take drug for 2-3 days if i gain a few pounds. this drug was extremely encouraging after being stuck in a weight loss rut.drink tons of water,you do not want to dehydrate on this! be very aware of mood changes and addiction."
