I'm feeling very impatient with my liver right now ; ))

don't forget that everyone's process is different... i got more stones out on the first few flushes (1-3) and then less thereafter (4-7). each flush is going to be different, and there are other things happening in there other than release of chaff & stones. even if you get nothing out at all for a few flushes, you're still clearing stuff, and getting ready for the next round of expulsions.
