Hi, this is my first posting so I hope it makes sense. I am a GI Nurse who happens to have celiac-sprue (great resource for newly diagnosed patients). There are many different preps for the colonoscopy. Golytle, Fleets phospho soda, pills etc. All do the same thing. The pills can be a little costly ($40-80). The Golytle is a lot of yucky tasting fluid and the Fleets is a more concentrated version of the Golytle. I have done all three and I did the best with the Fleets since I could chug 1 and a half ounces of the stuff, throw a GREEN Jolly Rancher candy in my mouth and then drank the water. You usually are also required to stay on clear liquids for the day prior to your procedure. Try and get one of the first appointments and stay home when you start the prep. Good luck and remember the prep is the worst part of the procedure. Hope this helps!!!
