"i have been taking phentermine since january 17th 2011, so far i have lost 30lbs! i did however change my eating habits drastically but in all honesty i couldn&#039;t have achieved it without the pill. i have completely stopped drinking soda since i started taking the pill, no sweets, no ice cream and no fried food. i eat lots of fish and chicken, every two weeks a small portion of red meat but all my food in cooked in the oven with no type of oil or butter or anything fattening. i do treat myself to something that i love every once in a while but i never eat after 6:30pm. i drink about 7-9 16.9 bottles of water every day. the only other fluids i take are milk and decaf tea but not every day. i exercise 6 days a week for 1 1/2 to 2 hours."
