"i have been using phentermine for 6 days now and have lost 8lbs.  i have used this before about 5 years ago.  i was 260lbs then and got down to 190lbs in 7 weeks.  i love this medicine. just very nervous, when i stop taking it the cravings will begin again.  currently, i am taking phentermine one hour before breakfast, eating a salad for breakfast (no fast food salad - they have a lot of calories, i am making my own), for lunch i eat a salad and for dinner i steam fresh veggies and grill chops, chicken, steak, and even eat crabs and shrimp (of course not all together).  i drink water all day, almost 16oz every hour, which is a big contributor to the weight loss, but i have always been an advocate for water, i never drink crystal light or diet sodas."
