I should be right at home here. 4:20am (Odd timing, but I'm not a stoner) and I'm still up. I've always been a night owl, but I think it got particularly bad once I took 3rd shift for awhile at my old job. I'll stay up gaming till sunrise some days, and then drag myself through work after a short nap. Don't know why I do it, I just enjoy the night. It's peaceful, and yes, I find I get a lot more done all around.
