I ended my short, experimental fast/cleanse yesterday and this morning had more mucoid plaque!
It was interesting because it was a rope about eight inches long in total (lots of nodules), but it was attached to a "plug" of psyllium. The rest has just come out by themselves. It was interesting to me to see with my own two eyes how the psyllium manages to get this stuff out -- it's like having some rolled up duct tape pushed through you that grabs hold of stuff as it passes and pulls it away from the intestinal wall. Very cool.
So my little three day experiment ended up producing roughly five feet of mucoid plaque.
