I agree with everyone else here about the blood rushing to your hands; and agree that bending them at the elbow with hands just half closed should help that for you.
As for the sleep issue -- it sounds like you are not happy with your schedule; do you want to change it? If you want to go to bed earlier and get up earlier; get an alarm and set it to get you up 30-60 minutes earlier each day and go to bed that much earlier as well.
Even if you don't sleep right away, lay there and rest anyway. Try reading before sleep and/or listening to low, soft music: they invariably help me sleep every time. Keep upping your bedtime until you get to where you want it and the same for getting up; it will take a little time, but eventually your body will get used to the change and wake itself up automatically.
Another trick is to leave your blinds open before you sleep, and the early light will wake you up earlier; that works for some people.
