A lot of people have nothing but liquid stools after the third day of Master Cleanse. This is because they have passed all the new waste in their system and either have no accumilated old waste, or it needs to be softened before it will break loose and exit. If you are over 35, it is probably the latter. On my first Master-Cleanse I had no solid BMs after Day 2, on my second I had some solids begin to pass after day 5 that were very dark and mucus-like. On my third MC, I had a few solids all through the cleanse, although it only lasted nine days due to problems. Just accept what you body is doing. Most fasting programs do not focus on bowel cleansing as strongly as Master-Cleanse and people still do well on them.
