Also, if you drink coffee, try cutting out any caffeine (includes coke etc) after say, 11am.
Perhaps also get a sleep app and have a look at your sleep cycles - I use https://www.sleepcycle.com/ and its taken me from "totally not a morning person" to waking up easy around 5am every morning. There's data recorded on how you sleep and if/when you snore, perhaps giving you some basic data on if you have sleep apnoea, which you would then get checked out too.
