Eat and drink something hot just before you crash out. if you are using a water bottle rather than a Camelbak type bladder, then fill it with hot water and take it into your bag with you. It also saves you having a solid bottle in the morning.
As mentioned before, unless things get dramatic, don't wear all your warm kit in your bag. It may help you get warm to begin with but by fcuk you'll be cold in the morning when you get out with nothing extra to put on.
Sounds obvious as well, but wear a hat in bed.
Survived at night at -12 in a Softy 9 with a meraklon liner, but wouldn't describe it as comfortable!
