One more thing . . . my best flushes are when I hardly eat anything at all the next day until dinner and just drink tons and tons of water. For a few of my flushes, as soon as I ate more than an apple, the stones stopped appearing and on at least one flush, I felt like craps. If you can't handle fasting that long, I can't emphasize how important it is to drink tons and tons of water the day of the flush. I use EmergenC all day long.
