"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."
