Keep a Normal Schedule
Perhaps the most important rule for people with insomnia is to keep a strict sleep-wake schedule, even on weekends. If you can't sleep one night, get up at your usual time the next morning and don't take any naps. If you nap, you'll have more trouble getting to sleep the next night, thereby compounding your insomnia. It's best to let yourself get good and sleepy so that it will be easier to get to sleep the next night.
