It was what, maybe in the 60s outside overnight? Had the AC running also as usual. I wore a very light sweater, pajama pants, and my ultra thick fleece bathrobe to bed. To add, I covered myself with a blanket, fleece cover, and one of those throw blankets I received when I donated blood. 

Today, did I wake up covered in sweat? You beat I didn't. I actually woke up like they do in commercials, all warm and toasty and feeling like you've been sleeping on a fluffy cloud. I chalk it up to being tortured just over 13 years ago in basic training when they would make us wake up in the middle of the freezing night to shovel snow around the buildings. That Chicago wind is no joke, and my body still remembers.
