Irritable Bowel Syndrome
"When I first started taking Bentyl it worked very well.  Aside from the side effects of being drowzy &amp; light headed it did the job it was meant to.  However, over the past year problems started to occur more frequently, thus stressing me out &amp; making the cycle continue.  I would up the dose but side effects worsen.  Overall it takes off the edge.  I give it a 7."
