Ooh, you have my sympathies. My entire family is sadly prone to kidney stones, and my mother has already had to have surgery twice to remove larger ones.
And Re: the holiday/religion thing? I'm an agnostic leaning towards paganism... and yet celebrate Christmas anyway. Go figure. It's all in the spirit of love and giving for me... religion has long since ceased to enter into it. But 'Peace on Earth, goodwill towards men'? That I can do.
Also, RANT = Release All Negative Tension.
Good for your health. Although I can't promise it'll do anything for kidney stones.
