I hAve been taking the medication for a little over three weeks. Started at 193lbs (I'm only 5ft tall) I'm down almost 12lbs. I do work out moderately, this week I've noticed a decrease in the amount I'm able to eat, so that awesome, but I'm finding I'm more intolerable to certain foods and then get diarrhea shortly after eating. I drink plenty of green tea, due to the dry mouth, and water when I work out. Anyone else experiencing this?
