"i started belviq on july 24 and in 10 days lost 10 pounds. i drastically changed my eating habits though, you must put in some work for the pill to work, i honestly do not believe though, that even with the change of eating, i would have lost that much in 10 days (i did not exercise in those 10 days). side effects - i had the worst headache for about 3 days, i just popped some aspirin and eventually the headaches stopped.  the one side effect that i did have that i eventually led me to stop taking beliviq is the tiredness!  it was so bad, that i chose not to take the pill anymore (stopped on august 1) and try to do this on my own, and so far so good. as of today august 20 i am down 13 pounds! outside of that, i highly recommend it!"
