"update on my experience.....i have been on it now for 21 days and have lost 15 pounds.  first weigh in at the doctors office.  i feel great.  no side effects.  at first was seemed very tired, but now i seem adjusted to the medication.  i take 75 mg at night before bed.  sleep better than i ever have.  appetite simply isn&#039;t there.  sodas don&#039;t taste the same; kind of like they have been sitting out for several days.  i am remain very hopeful this will work for the long term. i have approximately 100 pounds to lose."
