Do not drink alcoholic drinks when you're out in the wilderness in the cold. You may think it's warming you up but you're body is cooling down, internally, putting you at risk of hypothermia a lot quicker than if you had just drank water.
And over bundling up will cause you to overheat and sweat, causing the inside of your clothing to get soaked putting you at risk of frostbite. You should be just warm enough to be able to function and not shiver. But not feeling so warm you're breaking out a sweat. So, pace yourself when doing outdoor activities and don't over-exert yourself.
