"had lost 80 pounds from lap band and stalled with 30 lbs to go. dr recommended phentermine to get over the set point and i tried it. in 3 weeks i&#039;ve only lost 5 pounds. the constipation and dry mouth are huge but i haven&#039;t experienced any other side effects. but then again i haven&#039;t experienced any primary effects either. seems to me like if you&#039;re going to risk a controlled addictive substance the reward should be more than 5 pounds."
