colon lining?

I am new to cleansing, and have just started the B&P two days ago and have not noticed anything yet, and looking forward to great results. After I started this cleanse, I read on another site that the Bentonite pulls the lining away from the colon. Is this correct and if so how long before the lining is regenerated? If this is correct is it safe to have fecal matter in a "raw" colon? Tweet
