You can set your device to "turn-off" between the hours you set, whether on weekdays, weekends or both. . . . this way, if you're one who wouldn't want to be bothered by notifications as messages are received, your BB will be quiet and go to sleep as you had scheduled.
From Main Menu, go to OPTIONS -> AUTO ON/OFF
