It's probably too soon to be sure, but my last 2 cleanses have yielded no stones. The one before that yielded 3 small stones. My health improved significantly after flush #13. I *think* I've done 18 altogether, not counting the 2 eggnog flushes.
I still haven't had the nerve to eat ice cream, but I did have some scrambled eggs a few weeks back with no ill effects. 6 months ago, I was in agony at least 3 nights a week. Now, I'm sleeping through the night almost all the time. I still feel a twinge of discomfort, but nothing requiring painkillers.
I intend to do at least 2 more flushes before going back for another ultrasound. I didn't see much point while I was getting dozens of stones out with each flush.
