I don't partake, but one strategy I use is dreaming up of ideas at 'the witching hour' of 3AM in the morning, jotting down ideas, so I can work on them when I wake up. For some reason my mind races at that hour, so I take full advantage of it.
You often hear people failing to fall asleep because of racing thoughts, but jotting down those ideas makes me fall asleep since I got the ideas 'out of my system' so to speak.
