irritable bowel syndrome
"I switched from Bentyl to this because this is an extended release formula.  I tried it for 5 months and went back to Bentyl.  It didn't work any better and it dried me out so much I could hardly swallow.  After a bad flare up, I ended up at the ER and they thought I was very dehydrated but I wasn't, it was just the medicine.  I am going to talk with my GP about using something with phenobarbital as I have heard a lot of positive things about it.  I already take a migraine medicine with phenobarbital, so I should tolerate it well."
