I have done 7 flushes so far. It took until the 7th to feel substantial relief from most of my symptoms (allergies, pain in right side, acne). Some flushes would yield almost no stones, but then the next would yield many. It probably depends on many things (Where the stones are in the liver/GB, how much obstruction is in the colon, parasites, etc.). I strongly recommend Jim Foley's colon pills, colon cleanse, and Super phos-30 drops. You can get them relatively inexpensively at www.thebreathoflife.net/products.html. The pills and cleanse do a great job cleaning out the colon, and the drops soften the stones. I have ALWAYS had better results with these products than without. Either way, keep flushing. Perhaps if you are getting less stones, you might also wait a little longer between flushes. Sometimes the stones need to move forward in the liver and GB in order to be "flushable". Hope this helps. Good luck.
Oh... before I forget, always check your stool. This, not so pleasant, step might yield some surprises as stones often are mixed in with stool. Use a stick of some sort to mix it up. The stones should float to the surface.
