Since I don't always do the flushes to the letter, I usually don't get more than about 20 stones. To me it is still cleaning and I hope the accumelation will do the trick.
As far as the stone getting stuck, do another flush right away.
When I started out my stone was in the duct and is now free floating, according to the same ultrasound.
I have never done a parasite cleanse, I do mainly bowel and liver.
And eat healthier.
