What exactly do you mean by BM's? Do you mean "solid" BM's? because while you're on the Master-Cleanse that's not gonna happen. If you're doing SWF's you'll notice a little bit of solids here and there, but mainly liquid and that's totally normal. That's why this is called a cleanse - you're flushing everything out. Sounds like you're on the right track to me. Do you feel constipated?
