irritable bowel syndrome
"I've been on Bentyl for 3 1/2 years and my IBS is so much better when I take my pill. Initially I had severe dry mouth that lasted for about 3 months, but I no longer have that side effect. I take a pill one hour before I eat, and I can pretty much eat without worrying about a flare up.  If I eat a meal or snack with little or no fiber, my stomach gurgles and I get gas but no diarrhea."
