I use mag citrate for every flush ( natural calm) it tastes not too bad. I have done 3 flushes and have gotten out 200- 400 stones each time. I do not think I could choke down the Epsom Salts , I think the natural calm is much easier has a nice lemon flavor. I use 1 table spoon per each dose per 3/4 cup of water. I think that is the same ratio as the ES.
