"i started taking the generic version 6 months ago.  i had to go to my doctor every two weeks for a weigh-in and to &quot;earn&quot; another prescription (had to show some weight loss).  the first two days were the hardest with nausea.  i felt tired but had insomnia. i did lose 9 lbs the first 2 weeks, but after that i have only lost about 1-1.5 lbs/week.  i began working out 3-4 times a week for 30 minutes to improve muscle tone and cardio fitness. the dry mouth and constipation were bad, so i began taking the pill every other day which really helped. i did not notice any increase in appetite.  so far i have lost 40 lbs.  my doctor is thrilled and said i can continue with skipping 2-3 days. i plan on stopping when i hit 50 lb loss. i want to lose 100lbs total."
