So sorry your flush did nto go well. :( You may still see stones, some people have seen stones come out as many as 3 days after their flush!
If you're having diarrhea the same night as the flush, consider lowering the dosage of Epsom Salts . I don't like to have to go before the following morning, I think it really interferes. Could be you're very sensitive to the ES.
I also change the amt of oil/juice, as I'm just a little person. :) I take about 1/2 cup oil and 3/4 cup juice, that's it.
