I also manage to wake up before my alarm clock with 1-30 minutes (achieved via programming), with alarm times varying from 5.30 am to 7 am depending on what needs doing that day, but it’s still physically painful and mentally unpleasant. I’m basically running on autopilot until about noon. Oddly enough, if I manage to get a decent amount of sleep and wake up at something like 2 am, it’s awesome, but falling asleep at 5-6 in the afternoon is slightly difficult.
I cannot remember a single instance in my whole life when I woke up in the morning and thought ‘heh, fully rested and full of energy. what a wonderful morning!’. I cannot understand people able to get up earlier and do stuff like go running, before work. Hell, I shower at night to save time in the morning (and because getting into bed full of day-stuff is just icky). Going on holidays is also mildly unpleasant because hotels usually offer breakfast up to 10 am (11 in the weekend). I wish they’d offer brunch as well.
