I can remember as a kid ALWAYS sweating and being overheated...even in Jan. I would wear shorts to school in NE Wisconsin.

It all changed after I gave birth to my son. I can remember being SO cold that I could not get warm, even if I jacked the heat up to 80. It's better, now, but I still tolerate heat better and have less tolerance for cold. I usually can't fall asleep unless I have a heating pad draped over my hip.
