I did a very heavy psyllium powder/bentonite cleanse and having trouble getting some of it out. I press against the colon and I can feel it. I've done colemas and have gotten large chunks out but its still stuck and I can feel that I am not absorbing minerals as well as I used to. (Tooth enamel is weakening among other things). Right now I'm taking some cascara to see if that will shake things out.
