Embarassing Question

I am doing lots of cleansing that I have learned from curezone - psyllium and Bentonite shakes, liver flushing, and coffee enemas. Now I look in the toilet to keep track of how much waste is leaving my body. I am seeing a lot of these floating brown pieces of old fecal matter - probably at least 100 by now. What is strange is that they are all completely round - as round as a little marble. All of them have a little bit of straggling tissue that looks like a tail, that seems kinda like old mucus. These range in size from about 1/8th inch to 1/4 inch. They come out early in liver flushes, in coffee enemas, and in P and B's. I have cut several open, which is difficult because they are very resistant to being penetrated. Most of them seem to have little white hard crystals inside of them that seem like calcium crystals maybe. I don't know what they are or why they float, because they are extremely dense - they must have a lot of fat in them or something. Thanx.
