I'm really trying to convince myself to do one this weekend. My last flush was two weeks ago maybe even more like 3 weeks and the stones have quit rumbling. But now I feel like I have a baseball, no more like a hackysack under my right rib. I felt so good after my last flush. Even tempered and happy. Now I'm cranky and irratible and have a terrible headache but am afraid to take anything like Advil that might make the liver worse. Maybe I'll try some niacin.
