irritable bowel syndrome
"I have been dealing with IBS-C for the past two years now.  The Bentyl has decreased my bouts with IBS-C considerably.  I still get the bouts, but they don't last as long nor do they get as severe.  I used to have bouts that lasted days and were so painful I just laid in bed all day.  But now I need to find another secondary drug that will also help get rid of this forever!"
