I'm just getting back into doing flushes after a few years off. In the past, i successfully did Dr. Hulda Clark 's Liver Flush a dozen times. Now i've tried 3 & they are not working. Following all instructions perfectly as usual. The only change is that i've learned i have a sensitivity to olive, so i've switched to safflower oil. It's not that i'm just not seeing stones come out - it's the fact that i'm not even getting the diarrhea with the Epsom Salt water anymore.
