I mostly follow sleep best practices - no phone before sleep, sleeping at a regular time, meditation, blackout curtains, no caffeine after noon, etc and am able to fall asleep. But however I have a problem with waking up. I either need 9+ hours of sleep or I’m awake in just 5 hours - almost a bimodal distribution. The lack of consistency makes it very frustrating to plan the day. Considering I got to bed around the same time each day, not being to able to wake up on the same time is quite puzzling to me.
