I had a robotic partial colectomy almost two years ago after suffering from chronic Diverticulitis that eventually caused an abscess. Until I recently discovered Sunfiber, a prebiotic fiber, I continued to suffer with Diarrhea and unpredictable bowel movements. For me, Sunfiber was the answer. I still have four or five small, formed bowel movements a day, but I have both my freedom (to go out) and my energy back. For the record, I had tried Metamucil, Benefiber, Miralax, Organic Psyllium and stool softeners. No more gas or bloating.
