I'm an early bird -- yes, I admit it.
A few thing.
1) Go to bed early. As in, early. As in, if you want 8 hrs and you have to get up at 5, you go to bed at 8:30 (9 would be 8 hrs but you need to allow yourself a little while, say, a half an hour or so, to wind down and begin sleep)
2) Prep things before you go to bed so that you're not dragging in the morning. I find it's great to be able to just get up and go with minimal decisions and agita. So, for example, lay out your clothes the night before. Make your lunch for the next day (if you bring lunch), that sort of thing. Beats the hell out of learning at 5:45 AM that the shirt you wanted to wear has a stain.
3) Instead of staying up for TV, try TIVO or taping it. Except for something really attached to time, like a sporting event or the news, who cares if you get the scoop a day or two later? Besides, there's a lot of junk on TV in the earlier hrs so, instead of staying up until 11 to watch whatever, tape it and watch it at 7 PM the following day when there's nothing else on.
4) This is a great time of year to be an early riser, as there is light and you can really see things that are kinda cool. Yesterday, I saw 2 robins (in different places) with a worm in their mouths. Which was kinda cool, it really does support the idea of the early bird and all that. I also get to pet a lot of dogs out for their early morning constitutionals.
5) Good for you for not overloading on caffeine. I tend to do the opposite, have some caffeine in the morning and then cut myself off by the afternoon. I am trying, though, to get off the initial morning jolt as I think it's not the best thing for me.
6) Exercise is also good. Things are a lot better now that I do about a mile's worth of walking every AM as a part of my commute, rather than just drive door to door. Less stress that way, too.
And -- welcome to the early part of the day -- you get to see all sorts of funky things, like deer. Used to see wild turkeys at my last job (and, er, not in bottles).
