I have an update! I had my 3rd colonoscopy attempt yesterday (not counting the failed barium enema) and I FINALLY had a Dr. who could see the whole thing! This time they did a double balloon colonoscopy at a hospital. And the only reason I have blood in the stool is because it is very tortuous and winds a lot. But it's all ok and I don't have to get another for ten years like a normal person! I have had to do the prep four times this year and I'm so done with it. But I am also so very grateful that there's nothing wrong with me.
Just to help anyone else out with the prep I do add a couple extra hours to the liquid diet and I also use 2 fleet enemas after I finish drinking the swamp water. It worked the last two times and it's very difficult for me to get cleaned out. I usually take magnesium chloride and miralax daily for constipation. My prayers and best wishes to all of you having issues with this!
