I'm freezing too! I went out and bought some of those woolly sock/slippers things and they keep my tootsies nice and warm. I need to sit wrapped in a blanket in the evenings even with the heating and fire on!
It is the fact you have lost weight. It isn't necessarily CD. My Aunt lost 4 stone with weight watchers and whilst loosing her last stone she was cold all the time - we used to joke about her wearing jumpers even in summer! lol I asked her advice because I have been feeling freeeeeezing too (brrrrrr!) and she reassured me that it does go eventually. So i'm holding on (hot water bottle in hand) and hoping that the frostbite wears off very soon! Hugs x x x
