Don’t have the willpower for this? No problem. Disrupt your sleep more naturally. First, design your bedroom to promote sleeplessness: Buy a cheaper and less comfortable mattress than you can afford. Keep the room too warm. Ensure that intermittent noises from phones, e-mail alerts, and pets happen throughout the night. Have as many flashing LEDs on the walls and ceiling as you can manage. (Ask any hotel designer for advice on this one.)
