Yes they showed up on an ultrasound about 2 years ago. I had another ultrasound about 6 months ago and there were no stones, and I hadn't done any Liver Flushes in that time...just raw food and the pineapple juice. I did do 21 Liver Flushes about 2-3 years ago, but kept getting the gallbladder attacks, so decided to switch tactics.
Note - maybe the pineapple juice probably won't work for everyone (I don't know this for a fact - maybe it will??), but it sure worked for me. I'm not advocating that everyone rush out and buy pineapples, just relating an alternative that's definitely worth trying.
