I've taken to sleeping wearing a hoodie over my pyjamas and massive woollen socks.
Last night I put two heaters on either side of my bed so I wouldn't wake up with goosebumps in the middle of the night.
I've started carrying a hot water bottle around with me when I'm in the house.
I go out wearing tights under my jeans and aforementioned massive woollen socks.
When I get home I have to dry off everything I was wearing so I can put it on again the next day as it's the only good Winter clothes I have.
I'm also just about to make myself a big flask of hot chocolate to take into my room with me to keep me warm for a while.
This is the coldest Winter I've ever experienced/remember.
