Hi Mick, I wish you good luck! Is this your first colonoscopy? The prep is definitely the worst part - be prepared to spend LOTS of time (yes, even more than usual!) in the bathroom during prep. Make sure you have some entertainment to keep you occupied, a book or laptop computer or anything like that to keep yourself distracted while in the bathroom. I personally like to do sudoku puzzles and watch movies when I prep. Good luck with it, and I hope the scope gets you some answers!
