How to get more DEEP sleep?

I do A LOT to sleep well. Since becoming a mother I have been the lightest sleeper and have to do a lot in order to sleep well. I sleep in another room on work nights. Take an epsom bath every night. I wear CPAP, earplugs, Bluetooth face mask. I play binaural beats. Room dark and coldish. I take low dose melatonin, glycine, magnesium, LTheanine, baby dose of klonopin on work nights, CBD. I do not drink caffeine or alcohol.

Any other suggestions other than Rx sleep meds to get more deep sleep? They either do not work, have paradoxical effects, or make me way too tired the next day.

I was going to post a pic of my stats but I guess I can’t. For example, last night:

Slept 7h 31m

REM 1h 6m

Core 5h 29m

Deep 46m

Awake 17m

And this was a good night for me.
