I had the "Angel Water" colonic hydrotherapy as the colon prep for my annual colonoscopy (multiple polyps found so this has become necessary), and though I was very nervous that it would be "gross" and embarrassing, I couldn't have been more wrong. Angela was awesome and made me very comfortable. I did my own insertion, and she came in to check on my occasionally. She was always there if I needed her, but gave me the privacy that I also needed. The whole process was no big deal at all, and I didn't have to go through that horrible prep the evening before and spend my entire night in the bathroom with horrible abdominal cramping! No prep at all, other than drink as much apple juice as possible the day or two before. There was absolutely NO pain, nor even any discomfort - only relief! I will most definitely use this as my colonoscopy prep from now on, and I may even go occasionally simply for good colon health. Give it a try! You won't regret it!!
