In addition to good sleep hygiene and trying to get a sleep study as others have suggested, a white noise machine that you turn on only at bedtime is great as a “go to sleep” signal for your brain. It also should make you less likely to wake up from noise during the night.

I take gabapentin at night to help me sleep, and it works pretty well. It’s non addictive so I’m not worried about dependency. But it works well for me because of what’s stopping me from sleeping (nerve pain). Without pinpointing why you can’t sleep well it’s going to be hard to treat it.
