Look at the clock and calculate how many hours remain before you have to get up. Tell yourself that tomorrow you will desperately need to be rested, and that time is slipping away. Ignore the fact that you have survived past sleepless nights and that trying to force yourself to sleep is the best way to stay awake. Jettison any sense of equanimity and replace it with stressed-out urgency. This should allow you to lie there wide-eyed and alert until dawn.
