I've now done 7 of the Hulda Clark 2-day liver flushes, and 7 of Dr. Schultze's 5-day cleanses over the past 4 months. After 6 weeks I went back for a 2nd ultrasound to show I'd fixed the problem, and saw 3 huge stones (large marble-sized) and a gallbladder still "jam packed full" of stones. In my last 2 flushes I got out around 4 cups (!!!) of gravel-type stuff. I hear it can take a year or more to get rid of all of them, and I'm going to keep doing the flushes every 2 weeks. It works best for me while also doing a parasite cleanse. I had been drinking lots of apple juice (and doing Dr. Schultze's cleanse including lots of apple and carrot/beet/cucumber juice from my juicer) before the 2-day flush, but this time I did malic acid with just a few glasses of apple juice a day and had nearly as good results.
