I feel like my body just can't accept a static bedtime on a 24 hour cycle. I remember many a summer where I would operate on something closer to a 27 hour day which is pretty awesome but messed up in terms of integrating with the rest of society, which I assume most of us need/want to do. Also, I've never been a morning person - the closest thing I've had to a regular sleep schedule is like 3:30am to around noon.
Anyone else experience similar issues and shift their schedules accordingly? What helped out, and what kept it sustainable long term?
