Hot soup, many layers, woolen underwear.
Keep your belt on the outside of your jacket, then put a bottle (glass with aluminium screw cap) of real hot water down front in the nearest layer closest you can stand to your flesh.
A warm belly keeps you warm.
I'll be home before winter. It's too cold to sleep out.
I just tilt the seat back and throw a sleeping bag over myself. If I actually get cold......I start the truck! After all, your sleeping in your vehicle.

Yup.....and as others have said, layer up, and if you have a good sleeping bag you should be fine..I've slept in my -20 C bag in about -18 I think was the coldest, wasn't the most comfortable sleep but I wore my hunting clothes and a belleclava with a touque..helped a lot..
Scent control clothing, sprays, etc.. are all a sales scan, gimmicks to take hunters money. Research the studies, critters have incredible sense of smell. The only sure fire way to control scent is wind knowledge.
Have a fire, drink your beer, and eat some good food, then go out, and watch the wind.
I usually don't bring a cooler late season. If I do, its just a cheap soft one so any beer or water just goes in the sleeping bag by my feet.
Sleeping with a lot of layers of clothes as others mentioned helps too. I always make sure I have a dry set to sleep in.
Always think conduction. If any part of you is touching anything external it will just suck the heat right out of you.
Keeping my face warm has always been tricky. Often I will wake up with a numb face and put a blanket over it. The result is usually peeling a frozen blanket off my face first thing in the morning... crappy way to wake up. Ski mask or something that covers your face but has an opening for the mouth and nostrils is best.
