I have been taking 35mg 3 times a day (sometimes only 2 if I take it too late I cannot sleep at night) and I have lost 15 lbs in a month-with working out and eating healthy. I am going back to the doctor tomorrow to check my blood pressure, it was on the high side last time so I need to test it it ensure I can still take it. But I am concerned about gaining weight back when I stop taking the pills?
