Read a book.
Read this board.
Play solitaire.
Eat something that will make me crash in a few minutes.
Start a load of laundry so the sound of the machine lulls me.
Play my meditation CDs from InnerPeaceMusic.com.
I used to iron in the middle of the night, but since I don't wear things I *have* to iron any more, that's out as a bore-me-back-to-sleep method.
