"i have now been taking phentermine starting week 3. i have only lost 4 lb but i have lost inches 2 1/2 inches off my waist 1 1/2 inch off my hips. the day i started taking phentermine i weighed myself and measured myself. i have been working out 3 to 4 times per week, 1 hour of cardio on the treadmill and half an hour lifting light weight 5 to 10lb. i feel my body more firmer. it is at times discouraging that the scale doesn&#039;t say less but those are the breaks when you work out. but now i hope with at least losing some inches off my waist my family doctor and my obgyn can get off my case about my belly fat. i will keep working at it and post again."
