I just had a series of ten colonics once weekly for the past ten weeks. It was one of the best things that I have ever done for my health. And I have done a lot. I thought about getting them for years before I decided to go through with it. During the sessions, I would actually get areas that felt like bruises, very sore. After massaging, they would release slowly over time. You can always ask the therapist to leave you alone to relax after you are comfortable with the settings on the water. I much prefer the "open" system; I believe they call it Libbe. No getting up off of the table, at all. Make sure you are totally comfortable with the therapist, also.
