I can't comment about ice cream, but I did a second eggnog
flush a few days ago. It yielded 2 tiny stones and a
bunch of bright green slimy stuff. The first eggnog flush
yielded a couple dozen stones followed by very dark green
(almost black) watery stools that lasted a couple days.
I'm beginning to think that different fats do different
things to the liver and gallbladder. My largest diameter
stones were from an avacado oil flush. I haven't tried
that again because of the severe nausea.
