"i am on the 0.6 dose so far and been on this for a week. i have not lost anything and i eat 1200 calories or less every day, drink water and walk every night.  i think this only works if you are extremely fat or cannot control your eating because nothing has changed for me at all.  i am 41 years old 5&#039;4 and 196 pounds and i tried the belviq also with zero success.  this medicine does not work"
