See I'm the opposite. I've always been a night person as long as I can remember. Me going to bed before 1am means something is severely wrong with me. Like catastrophic.
My wife was that way 33 years ago. Worked nights. Took a long time to turn her around. She still sleeps to the absolute last possible moment. I have come to learn that if I cover the alarm clock and do not answer her obvious question..."What time is it" she will get up. Always fought for that last 5 minutes of sack time.
I moved my alarm clock over to my dresser so I actually have to get out of bed to hit the snooze button. I figured that would help. Nope. Instead I learned how to get up out of bed and navigate the distance to the loud buzzing thing with my eyes closed
