I'm sorry your sleep is so awful. That shit will break you down over time, and then everything just gets harder.
Alcohol is really helping you in several material ways, so in your position, I'd prioritize finding replacement strategies over anything else. Here are some suggestions I have from my own experience:
Prazosin for nightmares. Got this from a psychiatrist, it's low risk (a repurposed blood pressure drug rather than a typical psych med), maybe helps with effects of alcohol use as well?
This one is very much YMMV, but have you tried playing around while in sleep paralysis in order to reduce your fear of it? This is extremely difficult at the beginning because it will physically feel like (and you will literally believe) you are about to die. But when you're in sleep paralysis, allow yourself to feel the complete all-consuming terror without reacting and struggling away from it. If you feel your heart going a million miles a minute, it isn't actually, it's an illusion. (I usually do not have the feeling of breathlessness, crushing, or suffocation, but I'd wager those are illusory as well, because actual inability to breathe would wake you up fully.) Then, as the fear recedes, and it will eventually - stay with me here - peel yourself out of your body. Or roll out of your body, or pop up out of it. Now the sleep paralysis is over and you are having a cool dream, congrats. Because of this method, I actually look forward to sleep paralysis. But again, YMMV, not all sleep paralysis is experienced the same way.
edit: Forgot one thing. When you peel out, you may feel very intense vibrations. These are also okay and cannot hurt you, so simply observe like you do the other fearful sensations (much much easier said than done)

Hemp for sleep. I like to dry herb vape mine. Maybe at minimum this reduces how much alcohol you need.
Specifically this herbal tea which has multiple sedating plants in it:
