Hi
I get cold too. I use a hot water bottle but do not use boiling water with it, I stop the kettle before it boils. I cuddle it to my tummy instead of using it on my feet. I also wear socks in bed, my sister wears a hat. I also reccomend uniqlo's new range of thermal underwear. I don't need any of these though when I am snuggling with my boyfriend, he is always really warm.
