irritable bowel syndrome
"I've been taking this medication for over a month. I couldn't take it twice a day as that made my stomach hurt badly. I take 1 pill a day and works like a miracle. I used to look for bathrooms everywhere i went. It was embarrassing.  Almost had accidents several times because the diahrrea was so bad.

The only bad thing I can really say is that IF I miss a dose or take it late, my diahrrea comes back immediately with a vengeance. So just remember to be vigilant in your schedule. Otherwise, best medicine ever"
