LPT: have your last meal 16 hours before your breakfast. It's going to reset your cycle in one day and you're going to be able to go to bed and get up more easily the next day.

For example if you want to wake up at around 8am, eat dinner at 4pm, set an alarm at around 7:45 and eat breakfast at 8am.

Also what everyone else said are good tips to keep a consistent schedule, what I said is more like a soft reset, but you gotta practice not using screens at night, not drinking caffeine / not using nicotine (or any other stimulants that disrupt sleep) in the evening.
