I have to disagree on taking a break every 20 to 30 minutes being in conflict with getting into flow. If I apply the Pomodoro method and set a fixed time for the break to start, I found that for me it's actually quite easy to get back onto the problem after the short break. What I think makes the difference is that forcing the break, although annoying at first, makes you take the break when things are going well, resulting in eagerness to continue solving the problem after the break. While, if you take a break when you feel you need one, things are probably already stuck and it's harder to start up again. I do agree with getting away from the computer for a proper break every few hours, but isn't that quite natural already? I can't go without eating/drinking for much longer than that anyway.
