What I read Fuller did was simply catnap whenever he felt the urge. I also heard he never slept regularly again after starting this. I worked for an architect who spent a summer at Black Mountain, he said Fuller would just lie down and take a nap anywhere, even in the middle of giving a lecture (which I think was an exaggeration, being active, even just lecturing, is the best way I know of to stay awake and alert).
