"phentermine was just what i needed to help me lose the weight i needed to lose. i have high family risk of diabetes, high cholesterol, and stroke, so when my blood sugar showed that i was pre-diabetic at 168 lbs. my doctor put me on 1200-1500 calorie diet and phentermine. i&#039;ve always exercised three times a week. i lost 20 lbs. in three months and lost another 10 lbs. in the last year. at first i experienced side effects of dry mouth, trouble sleeping, and constipation by that subsided over time. i am still taking the medication, gong in for monthly weight and blood pressure checks, but lately have been feeling like it is losing its effectiveness. i&#039;m a little concerned about its addictive qualities and plan to ask my doctor about it."
