Well, certainly green slimy sludge IS a uniquity...and since I'm UnYquity, I didn't think you were calling me "green slimy sludge" (although I have been called MUCH worse!) lol Anyway, I just HAD to respond :)
To answer the original poster...if you're feeling gall-bladder contractions and movement, then most certainly ANYTHING you see that's green or yellow in your stones CAN be attributed to liver and kidney flushing and removal of stale bile, bile toxins and globules of fatty junk and cholesterol. Of course, when taking "green nutrients", our stools easily become green in color...but the yellow-green of bile is decidedly different (at least for me) than the 'murkey forest green' produced by green nutrients and supplements.
It sounds like you're doing great things! Keep up the good work :)
