One day my stool had small little light colored pebbles embedded in it. I had just purchased some Braggs ACV, so i think it was that. The pebbles would float if they seperated from the stool. The stool would sink. However, my forehead broke out pretty bad. Atleast it was a successful mini flush. Today im doing my second liver flush. Hope it goes well. (No colonics, or colema board. So i can expect to break out pretty bad on my forehead again...Its worth it I guess.) :(
