"i started the medication on 5/28/09 and its now june 9th.  i have lost 6 lbs in eleven days. i am happy with the medication and it definitely helps with the appetite. however, you do have to exercise and watch what you eat. i don&#039;t have those sweet cravings now. i have had little to know side effects. i really haven&#039;t noticed having extra energy but do have dry mouth.  i chew sugarless gum and drink plenty of water."
