Shifting waking time forwards is straightforward but getting into bed early enough can be tough. As for the phase shift, I've always had what I thought was maintenance insomnia but at some point I realized I always waking at exactly 4:30am. Going to bed early resolves the maintenance insomnia (also travelling eastward more than a few hours or so). My father and brother are the same. I'd love to get a DLMO done to confirm. Thinking about experimenting with tracking core body temperature monitoring soon. FWIW a 24h ambulatory blood pressure study actually showed a phase advanced nocturnal dip.
