I take PEG (Polyethylene Glycol) daily, the common brand name is Miralax. My colon shut down completely last year due to my muscular dystrophy and I had to be hospitalized to clear it out. The Docs there said if it continued they would have to carve out a new anus (which didn’t sound like much fun!). Since then I’ve taken PEG daily and have had no problems for over a year now. Good luck!
