Flush #7 - Nothing. Not a stone, not a flake. Until 24 hours after I drank the oil then I had just 5 small stones. That was it. For this flush I laid on my right side, knees up.
2 weeks later, went back to lying flat on my back. I felt nothing. I heard nothing (sometimes a gurgling sound). But the next day dozens of pea size and hundreds of smaller sizes.
Body position? I don't know. Also drank a cup of black coffee 2 hours before the Epsom Salts . (Figure I'd try it at the front end, instead of the back end as some have proposed. Don't know if that affected anything, though)
