I usually stay up for 36 hours or more, then crash for 10-12 hours. It doesn't lead to more productivity, but if you have trouble sleeping it sure helps.
My motivation to work usually clobbers me around the 24 hour mark, but if I fight through it, I can usually squeeze 4 or 5 more hours of work out of it.
I personally prefer to work for 20 hours or so, then do things I enjoy for 8 or 10 hours til I crash. This avoids feeling like your life is all work and no play, which will eventually lead to insanity.
Plus, it's easier to do marathon work sessions when you really need to since your mind is trained to stay awake that long.
