Date: 15/07 Alarm after: 6:00 Brief description: Woke up after 6:00 even though alarm was at 6:30. Stayed up for 30 minutes this time. Tried to wake my mind, and ended up using the PC. Then I was too awake and couldn't fall back asleep. Counted to 321, switched sides, counted to 87 and gave up. Why it failed/succeeded: Stayed awake too long during WBTB OR 6:00 is too long OR 6:00 didn't fit with any REM periods I guess I'll stay up for 10 minutes tomorrow, without any electronic devices.
