I am in the morning of my first cleanse (Dr. Clark's recipe) after a 10-day Master Cleanse. I've taken both morning doses of Epsom Salts and all I've passed so far is a lot of tan stuff--some of it floats on top of the toilet water (chaff?) and some of it has come out in solid chunks (but with no hard/green inside, just more tan stuff). It's kind of like Play-Doh in consistency. What is this? Bile? Why no stones?
