<i>I wonder if wearing a WakeMate may just train me to keep very still towards the morning hours of my sleep?</i><p>Maybe, but I assume you can just go back to sleep if you don't feel like getting up when the device thinks you should.   I do this with my alarm clock; I set it for a time that would be good to be awake at, but if I'm not in the mood to be awake at that time, I just re-set it for another hour or two.
