Hi Elis, I'll be doing my 3rd flush tonight (sipping apple juice right now as a matter of fact). There was a noticeable difference in my first and second stones. Like yours my first ones were brilliant green inside, with a brownish tan outer coating. The second stones were smaller, definitely not emerald green like the first, these were more gray-green. I am looking forward to seeing the stones from the flush I'll be completing tonight. I will add that I noticed more "movement" in my gall bladder area the eve of the second flush. It seemed that there was more "churning" than the first time, but that might have just been me noticing more through experience.
I have a question for you. I have noticed a real difference in the quality, shape, color, and odor of my bowel movements since doing the flushes (first one a couple months ago). I'd add that I also experience far far less intestinal gas than I ever did before doing the flushes. I am curious to know if others have experienced the same.
