Quick tips. Take a wide mouth Gatorade, drink it and use it for a piss bottle at night. Sounds gross, but you'll see when its freezing how much you want to get out of your tent to pee. Also, if you have to pee, just do it. If you fight it you'll toss and turn and eventually just get up anyway. Hot nalgene bottle is excellent in a sleeping bag to keep warm. Plus if its very cold you don't have to worry about it freezing and you'll have water for the morning. Widemouth preferred because the narrow ones freeze closed a lot faster. Also, buy some down camp booties, they are the shit. And you can wear them around instead of dragging muddy boots in your tent. Also, keep a little snackage close. If you wake up cold, eat a quick snack, it causes your system to work and generates heat. Like feeding a furnace. Good sleeping bag, propper clothing and the ability to make coffee in a vestibule really increases the happiness level. Enjoy!
