Irritable Bowel Syndrome
"After suffering most of my life from all the issues related to Irritable Bowel Syndrome, gas, diarrhea, chronic constipation, I have finally found I have a normal life with little or no gas, no more constipation, and rare loose stools.  But for anyone who has ever suffered from constipation, having loose stools is a welcome trade off.  Thank you Linzess."
