I don't think the green balls should be called stones. Maybe sludge balls and I do think the balls have the olive from the flush in them. I don't think I have heard of anyone on here pass a real calcified sharp black stone (if so please post pics).
When I found Curezone 5 years ago I was starting to have longer attacks from longs fasts and Andreas was the first and only one who suggested that going with out food with a dysfunctional GB could make it shrivel up and the sharp stones would attack.
I have been lazy about flushing and use the epsom and the olive oil regularly for relief and keep attacks at bay. There must be something about the flush that makes fresh bile and flex the liver because I do feel better afterward. The other weird thing is most people have attacks when they eat too much fat, I get attacks only when I don't eat fats. Andreas knowledge and similar experiences helped me so much.
I am in it for the long haul and hope to keep it up to avoid surgery. GB troubles are not fun.
It's probably not for everyone. Not sure if I would be flushing if I did't have these troubles. I still believe fasting is the way to go, my body says hell no.
