irritable bowel syndrome
"I suffered for many years with spasming gut: rolling waves of pain so severe I would be drenched in sweat, no control of explosive diarrhea.  I would be on the verge of passing out and have to lay on the bathroom stall floor in my own diarrhea.  Bentyl has saved me.  I was on a high dose at first, but slowly tapered off.  Now I take it as soon as I feel a bout coming on.  I carry it with me and it has saved me much public embarrassment.  It is a blessing."
