Sleep 1

(7:42 hours)

This morning was the second morning with my dawn simulation alarm clock. I woke up about 5 minutes before the beeper was due to go off and saw the bright light. Then I woke up to the beeper and turned it off, and once again dozed for about 40 minutes.

I think this could work when my sleeping pattern falls into a routine and when Yu Lee is not so tired. Either way, it's not worse than snoozing my alarm for an hour and is a lot more comfortable.
