Charley, I have read, and it helps me to have at least 2 bowel mov. before drinking the olive oil and grapefruit juice. I also keep peppermint to put in my mouth after I drink the oil, it helps with nausea. I have drunk a few sips of cola or ginger ale. If I don't feel well I don't lay down. I have done a daytime flush and stayed up all day, in fact there is one flush that you actually supposed to walk all day. I don't always find stones either but whether I go to bed or not doesn't seem to make any difference. If the bm is not (excuse graphics) "watery" I don't know if there are stones are not because I'm not willing to strain & wash bm. I've done 8 flushes and I've seen a few stones maybe 3 times but I plan to flush again. Hope that helps some.
