I don't have the answer. But I did read the worst thing to do is doing liverflushes and not continuing till all stones are gone. You probably stopped to soon, after the 6 months.
I would do them every 2-3 weeks. Also while you do it, do any of the bowelcleanses, just skip the the day of the OO. Liverflushes work realy well with empty bowels.
I use the Oxypowder .com">http://www. Oxypowder .com one., it is described under the superfos30 supplement.
