My experience

Heres some experience FWIW.

I have completed my 2nd flush, and got a lot of chaff.

A week later I still felt bloated and like I still had stones.

I went back on the 30 ozs of apple juice per day, and one morning I was up early so had my 30ozs and within an hour had to rush to the toilet. I had a loose bowel motion, but produced two 1cm wide stones of a light tan color.

I consider that a success.

Hope this helps - sometimes we have spontaneous flushes.
