obesity
"I have been on phentermine for 3 days. I have lost 7 pounds. HIGHLY due to the fact that I haven't eaten much of anything. I have walked everyday for 30 min a day. I take the pill when I wake. I have had a headache everyday about 3 or 4pm. I believe its because I am not taking in enough calories. I am also taking birth control and a women's multivitamin."
