Yes...I agree about the boulders...the longer the stones sit around in the intestines the larger they become, it seems! Clumping together.
Yep...if you didn't get out WAY more stones by drinking the extra oil, maybe stick to the regular amount. I mean, after all...the liver/gallbladder only holds so much bile right? So it's just one dose of fat that makes it expel the bile (pushing out the stones because of the pressure). More oil doesn't necessarily mean more stones because there's only so much bile in there to push stuff out with!
It's a good thing that the more oil we take doesn't translate into more stones...that would be kinda fishy!
