When you say "nothing, clear" does that mean no chaff as well? Those 100 stones you produced were probably formed in the six months since you did your last flush, don't you think?
I know I will have to flush my liver every six months for the rest of my life. I am prone to stones. And I WANT to flush twice a year - it is such a healthy thing to do. But I want to know when I can stop the monthly flushing.
