I find the same thing. My focus is much better when I remember to get away from the work take care of myself. At a friend's recommendation I started going to the gym when I feel myself drifting into procrastination. I was skeptical of the benefits at first but now it consistently clears my mind and sets me on the right track. I think it has something to do with the dopamine release that exercise provides. It might also be worthwhile to examine -why- you're procrastinating. In my experience, procrastination is caused by anxiety about the project I'm working on.
