I’m looking for suggestions that zombie-me could follow through with. The problem is I can barely bring myself to get out of bed, let alone do a useful task. It just wastes typically 2–5 hours of my life as I wait for tiredness to finally (re)take hold.
Move to the couch, and read a boring book if you can’t sleep. Don’t do anything stimulating or chances are it will make it harder to eventually go back to sleep.
