I did four Bowel Cleanses over about 9 months I think... I am starting to forget, I should read my old posts I guess.
I tried P&B shakes once (I mean one dose not a full course) and did colonix... I must have problems with fiber though as I had problems with bloat and did not feel clean after the full course of the cleanse.
I then did Oxypowder , which I liked, and then Colosan. For the money Colosan was the ticket for me. Worked as well or better than Oxypowder and was much more affordable. I bought 6 jars (months ago now) for $99 and still have four and a half left. Probably last me another year or more. I have only taken one maintenance dose in three weeks (and probably did not "need" it) even though they say you should take one a week as I have been very regular (for the first time since I can remember).
