I think your trying to do way too much at once. I have never done The Master Cleanse program, but I do recall hearing that the only additional thing that should be done with it is the saltwater flush every morning. You should not be doing P and B shakes with it, as that is an entirely different method of cleansing and it would interfere with the way that The Master Cleanse works. Laxative teas should only be used when necessary for constipation. They are very hard on the body when used unnecessarily or excessively. To use a laxative tea when on a fast might do more harm then good. The point of Master Cleanse is to naturally shed any old debris from the GI tract without the use of harsh herbs such as senna.
