This was Flush #10 for me. I tried the coke and lemon juice flush this time. Im doing it from now on. It worked much better for me. I didnt get sick, I slept much better, and I got a dozen larger stones and about 20 baby ones. This is good for me. Just thought I would post for anyone interested in trying it. Oh, and I used Oxypowder not ES. I started usisng Oxypowder in place of ES a few flushes ago and it does me much better too.
