I do onganic coffee enemas for 3 days, the day before flushing, flushing day and the next day to make sure the passages are clear and that I get everything out.
I don't count stones, I measure them. Usually I get a good 1/2 cup out. I hope to be nearing the end after 35 flushes I do look forward to it. Last time I got a little less than 1/2 cup. I hope that I don't have to go past 40 flushes. :-)
Good Luck, Giz.
