Have you ruled out gluten sensitivity and other intestinal problems that may be causing you to make more stones as you flush the old ones out. My problem was undiagnosed Celiac Disease and Leaky gut caused by gluten. I have stopped making as many stones since I went gluten free 5 years ago. Once you find out why you have made so many stones then it is just the process of breaking up the solidified sludge and getting old stones out. And, of course, keep on using parasite herbs to get out the flukes. And learning to prevent reinfestion by parasites.
