Congratulations, Bundles! Getting all excited over what's in our toilet bowls is like being a child again, isn't it! I was like you when I passed a few calcified stones after a liver flush.
Uniquity, you are a caution! :) A most amusing writer!
Re kefir. Not everyone is sensitive to dairy. I love a bit of kefir, it doesn't bother me at all, on a hot day with a wee pinch of salt. Homemade, of course.
