Thanks BOB and Southern Belle. You've convinced me. I am still going ahead with the juice fast, but adding a colon cleanse. It sounds like the B/P shakes are the best, but my local health food store had the P but not the B. So I am using a similar product with psyllium, trifalia flax seed and some other stuff, plus Smooth Move tea at night. I will have to special order the bentonite.
I feel really good this am, after a 60 hour Water Fast and my first glass of fresh pineapple juice. I can only describe the feeling as very clear and calm. I am hoping I will enjoy this!
