Eating before bed works for me...although the trouble I have is that if I move around much before going to bed, it can take hours for me to fall asleep.
I have severe insomnia a lot of the time and if I get up and exercise before bed, forget it. I may have hiked thirty or forty kilometers with a full pack that day, and slept four hours the night before, and the night before that...but now I'm going to be awake until 3 am.
Quite annoying! I always need to bring books when I camp so that I will have something to do between ten pm, when I usually head off to bed, and two am, when I usually fall asleep.
There is always the option of staying up until two...but then I won't sleep until four (a two hour improvement in a sense...but not very useful at the same time!)
Unfortunately I am not one of those people who only needs a few hours sleep each night, either! I am pretty functional on two hours of sleep for weeks at a time but I really don't feel happy unless I am getting close to eight.
Still, it's much better out in the wilderness than in the city, where I sometimes miss a complete night of sleep once every two weeks. I am always caught up on my reading but doing ten hours of physical labour on Friday after twelve hours of sleep total during the week is more than a little draining!
Anyway hijack over...I would guess a tent is good for 10f in nominal wind but as you say, high winds is something else altogether!
My old Canadian arctic setup was barely tolerable in -15 when used without a tent. I had most of my clothes on, a toque and a nice prolite 4 mat, and man, you wouldn't have wanted a single feather blowing out of that system!
Of course it was fairly windy, come to think of it.
