Just saw this! I had a high colonic as they are called here, when I was 19 (46 now), it was just a few years ago.... Yes, they gently shove this hose in your bum with two things (prongs?) on it, one to put water in, one to take the water out. The liquid was all enclosed in the tubes--there was no sewer smell at all for me, very discreet, but if you look at the tubes, you can see stuff coming out of you for sure! They massaged my lower stomach and colon each step of the way as they can get the water to go further and further into your large colon as they clean you out. I did not find it extremely comfortable, but at that time I had not yet given birth which does change your perspective a bit on painful procedures! I did feel better, but can't actually remember how much better I felt as that was a lifetime ago. My massage therapist has recommended that I go for one and she has someone that she really likes, so I might just have one myself sometime in the future. I hate having anything pushed up my a** , so I have avoided this procedure for the past 30 years or so Coddy! I know.....anything to lose a pound, right? And it is so romantic! His and Hers Colonics!! Maybe you could be laying next to each other when they do it!
