I never need my alarm clock to wake up since I always wake up before it goes off, but I need it to go to sleep. If I don't have an alarm set I wake up all through the night and check the time. Knowing there is an alarm set, even though I never sleep until it goes off, removes anxiousness that otherwise prevents me from sleeping well.
