In all the years I have been around I have never heard of anyone complaining of this issue on the MC. Now I did have that issue but it only happened on one MC which for the last 7 days of a 40 dayer I decided to finish the MC as colon cleanse and did OxyPower. I developed the mother of all hemorhoids and I attributed it to the Oxy since I had never had that issue or never heard of anyone else while on the MC.
