"i stopped after 15 days due to constipation and  abdominal pain. i lost no weight. it did nothing for me at all. after i stopped i went on an uncontrollable binge for several days. i was eating things i hadn&#039;t had in a year - ice cream, chips. i felt out of control.   i went back to the phentermine and that has helped stop the binge eating.. i wish i had never tried this med and wasted my money."
