I've always been a champion sleeper, but since I started using a sleep mask I took it to the next level . This morning, for example, I don't have anything scheduled. I got up at around 0630 to take care of the dogs and stayed up for about an hour before going back to sleep. I had the window open for a nice breeze and blindfold in place, and woke up about 1045. Go me for a Sunday morning.
 I hate this overused and trite expression, but it worked for me in this particular instance.
