I've had the same problem!!! I'm usually a REALLY hot blooded person, but lately i just can't seem to stay warm. I usually break a sweat in 50 degree weather, but i just can't seem to retain any body heat whatsoever. I sleep under 2 comforters lol. DH has had to sleep on the couch lately, because he gets SOO hot.
Funny what something the size of rice can do to us huh?
