Alarm for One

My wife and I go to bed at the same time and never, ever, ever get up at the same time.  She often complains that I hit the snooze button to many times.  The answer is to get an alarm clock that only I can hear.  I have two solutions.  The first is to have a small alarm clock built into your pillow.  Then the noise it makes will only wake you.  The second option is a sock that gently squeezes your foot with increasing pressure until you wake up.
