Me and sleep have a very bad relationship with each other. But it goes on and off so its never been constanty bad. Ever since I was a kid, really. Over the years there's a couple of things I've done to cope:

I get very intense voices at night. Always have. And I used to try to shut them off. But the effort of trying to control something I couldn't was just frustrating and actually kept me awake MORE. So eventually I learned to just "let them talk". And it helped quite a bit actually. It kind of made a soundtrack to fall asleep to, and every once in a while I can hear something good. Not sure if you experience that as well, but thought I'd mention it.

I've worn earplugs to bed and that helps if your trying to block out ALL ambient noise as I sometimes find it distracting. However, this DOES tend to make the voices from the previous example much worse.

I've most recently downloaded an app that plays rain, waterfall, ocean sounds things like that and it REALLY helps. But I find it doesn't help keep me from waking up in the middle of the night.

In severe cases I've taken nyquil. But my go to was tylpnol PM. (pdoc recently prescribed Trazodone but I haven't tried it yet.)

If you can, try to force yourself to stay away during the day or at least from 1 or 2 in the afternoon until bedtime. This might help also.
