I didn't think you were serious about a 7pm bedtime. It honestly sounds absurd
to me. I can't see it working with anyone except infants.
Maybe that's a solution for a problem that I've never experienced. No one in my extended family has a problem staying asleep once they fall asleep. Going to bed at 7pm would be a surefire way for me to wake up at 3am and be completely exhausted by late afternoon the next day.
