"i have been on qsymia for about 5 weeks and lost 15lbs. while i am very pleased with the loss, i have had a lot of cramping &amp; extreme diarrhea for the past week. it started out always hitting me about 7pm &amp; then increased to mornings and then during the night as well. has anyone else had this problem. i am calling the dr., but haven&#039;t seen anyone else with it and wonder if it could be caused by something else. i don&#039;t really want to give this up yet."
