LPT request : sleeping through the night

Any recommendations on staying asleep or falling back asleep quickly? I keep waking up an hour or 2 before my alarm

Update:

Thank you everyone!

I have used ear plugs and sleep masks but dont anymore because they keep coming out/off my face.

I currently use a body pillow, weighted blanket, fans, and a sleep schedule. But it is not as cold as I would like it to be.

I dont drink any caffeine, but I do enjoy the occasional tiki drink, but when I do drink, it tends to be with brunch, so there's at least 7 hours before I plan to sleep.

I don't eat 3 hours before bed, don't drink water 2hours before bed, and don't smoke weed, or use screens an hour before bed. I take a shower to unwind before bed.

My alarm is on my phone so I have to keep it near, but I do have anxiety about sleeping through the alarm / the alarm not making sound when it goes off because both have happened before. Any advice? I have to be at work at 6am, going to bed at 9pm.

I will try to drink more water during the day, but not within 2hrs of bedtime
