My doctor asked me at my follow up visit do I still get really hungry and I replied yes. She wrote me a prescription for this medicine and told me to start taking it right away because I wanted to get scheduled for my Bariatric Surgery. In order to be considered for the surgery I needed to lose at least another 10 pounds. I started taking phentermine on January 25th. I lost 8 pounds in one week. Today is February 10th and I have lost over 20 lbs. This stuff is amazing. A little dry mouth. Never hungry. I am scheduled for my surgery and excited. I recommend phentermine to anyone that really wants to lose real weight!
