Just got my instructions for colonoscopy prep. I was wondering if anyone else has had the same prep. It is SUPREP Bowel prep Kit. You add this to water, total 16 oz and drink all liquid. You must drink 32 oz more of water within an hour. You repeat this process at 3am the morning of. Also 5 days before colonoscopy you can't take any herbal supplements or iron supplements. (Does that mean vitamins?) It also says no solid food the day before, just clear liquids. Has anyone else done this? I don't know how I'll drink all that liquid in 1 hour and the 16 oz right down. And not being able to eat solid food for the whole day before?! Anyone else do this prep? Thanks for any info.
