Yeah, I know that already. I too have done lots of flushes when nothing has come out and this is probably due, as you say, to the unpredictability of the intestinal environment at the particular time of the flush.
However, I mean flush clean permanently. After all, the theory is that these stones block bile flow, so it makes sense that even a few stones blocking the bile ducts should cause original symptoms to re-appear. Now, if these stones are not stones, and there is in fact nothing blocking the bile ducts, what are we doing? Just drinking oil to release lots of toxin-filled bile to provide temporary- and ultimately- artificial improvement?
Now I know the Curezone site is very clear in its exclaimers, but someone with a serious disease like Cancer really could be led up the garden path with this type of treatment. I also don't think Curezone should give forums to people like Andreas Moritz , who used it basically as an advertising tool and took off when he thought he had exhausted it as advertising avenue, or when he had made enough money.
