"i am 19, 5&#039;8, &amp; was 260 lbs. i just started phentermine 2 weeks ago. i try to exercise at least 20 minutes 5 days out of the week &amp; eat healthy meals. so far on this medicine i have lost 16 pounds so i am currently 244 lbs. i really don&#039;t have an appetite &amp; have to force myself to eat. only side effect is a dry mouth and a bad taste in my mouth, but that&#039;s nothing gum can&#039;t fix! love this medicine so far."
