I'm a lot more alert nowadays, so much so that I'm cutting down on the video games and starting to do more productive things. I'm still a little groggy when I get up from my core sleep at 4-ish, but it's getting better. This morning I watched the first episode of Firefly (on hulu), a show I've been meaning to watch for a while. That kept me pretty alert.
I'm pretty happy that this is working out so well.
