Thanks, Raindrop. What you've described is exactly what I'm concerned about. I cannot stay asleep for more than 3 hours at a stretch...which seems to me to be indicative itself of a sleep disorder. But I'll be annoyed of I show up only to be sent home in a few hours. Oh, well...guess I'll just hope for the best.
Oh - and it freaks me, too, about people watching me sleep. I mean, who could be comfortable with that?!
