This post is nearly a mirror image of myself! I tend to relax on the major holidays (xmas and nye), but everything else is the same. My brain is constantly working on some problem that is of interest to me. I have time to do side projects because that is what I do for fun. I have the same sleep schedule as you (I work in Cambridge, MA but live West of 495), although I'm not sure if I'd voluntarily choose it. Working alone in the mornings is quite productive though. And I second the sentiment "it's important to switch off for days at a time." I expect much of this will change when kids come along though. ;-)
