I wonder how long a person can go without sleep? Dylan refused to go to sleep until 11:00 p.m., and was up to eat at 1:30 a.m., didn’t go back to sleep until 3:00 a.m., and was back up at 6:30 a.m. Thade was up late too, and woke right up at 6:45 a.m. This has been going on for over a week now, and I’m beat.
