From Day 1, my BMs have been light colored. I only passed dark-greenish residue doing a Vit-ra-tox cleanse a week and a half ago. Since I got not ropes then, I thought maybe I'd trying something else. I would think that if it were liquifying the old MP and Fecal material that it would be dark. I've been having on-and-off butt pee , and no-form, light tanish colored BM since Day 1.
