"i have been on this medication for about 3 months now and am down 19 pounds - i was super excited at the beginning but i haven&#039;t lost anything in about 2 weeks even with increased exercise;  i wonder if anyone else is experiencing this.  i am having a terrible side effect which i haven&#039;t read that anyone else is having and wonder if maybe it is out of the ordinary.  i have terrible gas (burping) that smells so foul it wakes me up in the middle of the night.  the only way i can control this is with pepto bismol;  i wonder if i am the only one who experiences this.  i can live with the side effect because of the weight loss."
