Bonus tip re: your last bullet is just try and lay in bed and keep your eyes closed, almost like an extended meditation. I let my mind wander etc not like a structured meditation, but just try and physically rest. This def takes the sting out of lack of sleep.

Also, a big part of dark bags under your eyes is not letting them rest. This helps a ton with that even if I’m only getting a handful of true sleep hours on a given night. And psychologically, not having the “heavy eyes” feeling helps when I’m awake.
