I think we get more stones out on the first flush, if you have a gallbladder, because they are stored in the gallbladder. By the second flush the bladder should be empty and we are pulling them from the liver. Then we don't get quite so many. I haven't looked at the posts of people who did 2 & 3 to see if they got tons, in the hundreds, the second time around. If it were within 2 weeks. Someone told me that it only takes the liver 8 hours to build up the bile again after eating fats. That's from 2 pm to 10. Anyway, he has 12 less than he had before.
