Oh my gosh I feel so sorry for you. I just had a colonoscopy and my miralax/biscodyl laxative prep did not work. Anyway someone on this forum suggested I hold my nose an chug it. It actually helps some. I have decided if they don't come up with an easier way to prep I will not have any more colonoscopies. I am soooo over it. I always have drama sourrounding the stupid prep. They do have 5 pills you can take with like a galloon of water but most gastros will not prescribe it (kidney damage I think). I used it once and it was the only time I have ever been completely cleaned out for a colonoscopy. My new dr refuses to use it. I guess sigmoidoscopy will have to be enough for her then.
I will be routing for you to get it all down. I know it is horrible.
