I've been battling diverticulitis for several years. I had 12 inches of my colon removed. I've had 8 colonoscopies so far. Number nine is soon to be scheduled. Diverticulitis is truly an evil affliction!! So eat yer damn fiber people!! It is a low fiber diet (aka typical american diet) that causes diverticulitis!!

And yes the latest prep/process for a colonoscopy is a minor event in one's life.
