Flush #6 had moderate results, dozens in the 1/4" range. Flush #7 only yielded 5 small stones 24 fours after taking the oil. Absolutely nothing in the preceding hours. 2 weeks later, flush #8 yielded a few dozen stones above 1/4 inch and hundreds of smaller stones. The only difference between 7 and 8 was body position. Right side on 7 and on my back for 8 (#8 included a cup of black coffee 2 hours before the Epsom Salts ). Been feeling pressure, though, on my lower left side, building for the last few weeks. Sometimes I feel it, sometimes I don't.
