Pay attention to your sleep cycle, so you don’t wake up in the middle of deep sleep. And as others have said, wake up early the day before so it’s easier to fall asleep
I think I used to use this website to try to figure out when I should go to sleep based on when I needed to wake up. I eventually stopped because I got to where I could figure out 6, 7.5, or 9 hours + 15 minutes on my own (or even 3 or 4.5 hours if I made poor decisions about when I’m going to sleep). It seemed to help.
