clay in a capsule?

I tried the fast last week and blew it after 3 days. but i want to try again, now that things are calmer. I have never tried the B&P shakes, and dont hink i could get one down. While in the health food store getting the syrup i saw a product that had the B and the P in a capsule, HAs anyone tried them? do they work like the shakes? Thanks
