We've completed our flushes with success--#2 for me and #1 for my husband. My husband passed about a half cupful of stones the size of chick peas and a lot of sludge.
I passed slightly bigger stones this time (also chick pea size) and tons of sludge (about 1 1/2 cups). I know this is from somewhere because I have fasted for four days and my bowels were absolutely clear. Also, physically, we are both feeling fine. Unlike my first time when I was absolutely washed out the next day -- but that could be because I got my period at the same time! Also, the color of the stones were a dull green and the sludge tan. My first go I had brilliant green stones (rather pretty!). I also noticed that the larger stones were clusters of smaller ones.

All in all, I am thankful that we had successful flushes and hope to keep going.It's all bad stuff coming out, thank God.

Cheers.
