I think what Demi was referring to is your rather "Doctorly" advice. That never goes over well here. But please don't take offense. We need to help each other understand the problem.
Regarding intrahepatic stones being rare -- this is just plain wrong. The medical dogma is partative -- it wants you to think that everything is separate from everything else. Not so. Stones are formed in the liver and find there way to the gallbladder. The gallbladder is you ally, it helps you pump out the sludge. After gallbladder surgery it's a constant struggle to keep the pipes clear.
