I'm at the end of day 9 of my cleanse. I just found this board a few days ago. I've been drinking psyllium and bentonite shakes for at least half of the 9 days (and, other than that, following the Master Cleanse instructions completely).
Now I read here that psyllium and bentonite should not be used in combination with the Master Cleanse.
For those people who (similar to me) like to know why not, here's a link to some information I've just found about this (it gives a number of reasons):
I'd have preferred not having to drink those P&B shakes (I find them a bit yuckky)!! But I've still benefitted from my less-than-perfect cleanse, and still plan to end it after tomorrow. (The next one will be P&B free). I'm a little bloated from the psyllium, but the white coating that I've always had on my tongue is partially sloughing off. I was feeling really good up until a few days ago, when I started spending all day at this computer reading up on cleansing and raw foods...there's SO MUCH to learn!
