> if you don't want to get a kidney stone (and believe me, you don't)

To put some perspective on that, I recently had one and it was the worst pain in my life. I asked some women who have had both a stone and a natural childbirth which was worse, and they said the pain is about the same.

The difference is that at least you know +/- about a month when you're going to have a child and can prepare; with the stone, you're just suddenly in excruciating pain.
