Yep, they are a lot of us like that, each trying to deal with it in their own way. I think it's the nature of our occupation: staring at a computer screen for hours is probably not the most natural thing ever. I really like factorialboy comments about meditation. For my part I've had a look at http://www.pomodorotechnique.com/, looks like it's working pretty well for me, simply taking short break between short working sessions.
