Hi Chexi
Congratulations, you did it,and quite sucessfully. Like someone else's experience above, my 2nd flush produced considerably more stones as well as my first, including some large ones, which there were none of in my first flush. So yes, keep on flushing, you are on the right track.
I had mixed grapefruit juice into my Epsom Salts , quite palatable that way. Next time will have a couple of mouthful of it also ready to chase down the oolivr oil taste
Good Luck!...
