The past five Liver Flushes I've only got a dozen small stones and several larger than a pea. Occasionally, I get some out the size of marbles. I have done some 16-20 Liver Cleanses and always get much chaff the morning after the third cup of MgSO4 water.
About six flushes ago (~2 years) I got out between 150-200 BB size to larger marble size. That was my best yet. Once I did the Coke Cola cleanse and it pushed out a C battery size plug of green sludge out - very surprised. I'm actually do for a liver cleanse. Prob get to do one in about five days.
