I can’t remember why, but I stopped using a traditional alarm clock and started using my Blackberry to wake me up…the plan worked beautifully until I realized that I had a snooze option on there…that was the major flaw in my plan. In my deep REM sleep, I frequently hit turn the alarm off instead of snoozing…and, then wake up LATE! This might annoy me, but it also might help…if you hit snooze once, this alarm clock rolls around the room until you turn it off. I think it can even jump off the nightstand!
