Your bed should only be used for sleep and sex. If you continually use the bed for activities that are not conducive to sleep, like reading, eating or watching television, you may find yourself too tempted to pick up a book or reach for the remote when you should be settling down for sleep. In fact, if you're not tired, don't go to bed. If you are unable to fall asleep within 15 minutes, get up and do something that literally bores you to sleep. Return to bed when you're tired and closer to sleep.
