My first flush was 1 1/2" layer of floating stuff..
Not many stones at all, Found out it was cholesteral..
And even tho I have done 6 flushes I still have 80% cholestral over stones..I got more stones with 3 & 5 flush then the rest.
I know its from Microwave Food but at this time I'm working 2 jobs & can only deal with so much..
