"i stared phentermine on march 21st i was 196lbs i take it every day first thing in the morning and then i eat breakfast 2 hrs later. i workout (cardio) 45 min 3 or 4 times a week. i have to say that i am not on a real diet i eat ice cream or pizza once in a while, 12 glasses of water every day and now 6 weeks later and lost 22lbs (now 174lbs) i feel great. before i started this pill i was diagnosed diabetic! (25 years old) now my a1c is back to normal! and my blood pressure is perfect. i am still working on my cholesterol! i also had problems with my period after the weight loss is back to normal. i love the energy this pill gives me. but i&#039;ve noticed the day i don&#039;t take the pill i get a terrible headache."
