this was similar to my experience. I felt very drained on day 2 (day after the flush), but after another night's sleep, I woke up feeling absolutely terrific.
I think it would do some good to find out what the stones were. If, for example, I found a stone that sank (assuming what pathology-guy says is true), have that analyzed and prove that its a gallstone, then that will prove that this method can pass gallstones, not just soap. Then the mystery of the floating stones won't matter really.
I'll see what I can find out about getting stones analyzed and post the results.
