"Stones" that you can't crush with a spoon or won't 'melt' are usually true Gallstones (calcified or partially calicified). What most folks on Curezone refer to as 'stones' are actually compact/hardened globules of fat, bile, cholesterol & toxins.
It sounds to me like you successfully got rid of some Gallstones (along with the rest of the stuff)...and that's a really good thing!
Pay close attention to your liver/gallbladder now, especially for the next few days. When we push out stuff/stones with our flushing, many times there's a lot left in there...and you may be sensing stones moving forward or loosening, now that you've given them room to move around & exit.
If you run into any pain or discomfort, usually a couple of teaspoons of Epsom Salts in a glass of water will relax the biliary ducts enough to get immediate relief (along with some diahrrea from the ES).
