Phentermine
"I was 20 pounds overweight, not much for some but for someone who has never been overweight. It was traumatic.  My doctor prescribed phentermine - 1 per day - 30mg capsule - for four days per week only for 12 weeks.  I also changed my diet, counted calories, eliminated breads and sweets, and added a different exercise 4 times per week. I lost 15 pounds in 12 weeks. I probably would have lost more but I went on vacation for three weeks during this period. I would recommend this medicine to anyone who only needs to lose a small amount of weight."
