Thanks for the anti-boredom tips, glenntaj. A good book or interesting programming (I'm an NPR fan too--Wait, Wait, Don't Tell Me and This American Life are my favorites) can sure help!

And yes, mrsD, that's what I was trying to say about the high BUN/Creatinine, that it was probably just dehydration. But I thought in my Googling I read that it could be associated with renal failure, which scared me. I think that maybe it would be easiest to get it tested again when I'm sufficiently hydrated, and if turns out normal, I'd have one less thing on my list to worry about.

And glenntaj, thanks for the link. I will look at it right now and learn what I can.

I really appreciate everyone's input!
