Questions
If I go to bed at 9:00 PM, what time should I wake up?
Wake up at 4:44 AM for 5 full sleep cycles (7 hours 30 minutes) or 6:14 AM for 6 cycles (9 hours), assuming about 14 minutes to fall asleep.
Is 3:14 AM OK after a 9:00 PM bedtime?
3:14 AM is 4 cycles (6 hours), so you'll wake between cycles, but it's under the 7+ hours adults need. Fine occasionally.
