Thanks to everyone for these posts - I am a newbie, first day on this support group/forum, and 2 months post-surgery (20 Oct 2014). I have been freezing ALL of the time. My family is so hot in the house that here in Colorado in December, they are opening the doors to cool the house down because THEY are so hot - since I have tried to tweak the thermostat now and then! So now that I read all of your posts, it makes some sense. Thanks also to the folks who provide some URLs with external links, made for some interesting reading. Thanks again!
