I did flush #2 last night and saw the same thing this morning when I did a SWF (Salt-Water-Flush) after dose #2 of Mag. Citrate. Also, in your experience, is ES more effective than Magnesium Citrate? The reason I ask is that I am reading the posts about the taste of different components, and I find the OO/LJ a walk in the park compared to the ES, which tastes to me like drinking a beer can, without the beer. Mag Cit is so much easier, but I'll put up with the taste for the better results.
I used the ES on flush#1 and seemed to have more stones then, especially the emerald green cholesterol ones although I did not do a SWF (Salt-Water-Flush) on the first. Even with fewer stones coming out I do feel somewhat purged of toxins though.
