Step 5: Get Warm Fluids into You

This is probably the most pleasant step. Sitting out in the cold after a long day of communing with nature, there's very little that's nicer than a warm drink. I personally prefer tea, but hot coco and hot drink mixes such as apple cider or gatorade are also favorites. The purpose of this step is twofold: it warms you up and it hydrates you. There's virtually not part of camping that is worse off for better hydration, and sleeping is no exception. Don't overdo it, though; a cup or two is good but past that you're probably in for a nighttime hike to the tree. You should also eat something, obviously, but if you haven't figured that out you probably shouldn't be camping.

If you're going to bed, you probably want to avoid caffeinated beverages for two reasons - 1) sleeplessness and 2) having to relieve yourself in the middle of the night and thus possibly losing all the warmth you've built up in your bag.
Also caffeine Dehydrates you. Never a good idea to have caffeine on a hike.
 I've heard eating foods with high protein before you go to bed can help in keeping you warm during the night. That is why foods like stew work so well.

If you are sleeping in cold weather you want to get some amount of sugar in you to keep your internal temperature up. This candy or whatever you eat will help by keeping your digestive system working for the first few hours while you are heating up your tent.

A trick I've used when hypothermic and with a can of stew for dinner: I got into my bag, heated up the can in the cooking pot with a little water, then brought it into the bag with me. Reheat and repeat until warm, then open the can and eat the warm stew.
