Something that has worked surprisingly well for me is journaling via voice recording on my phone. It's been so effective that I've mapped it to my phone's physical shortcut button.

I have struggled with on-and-off sleep issues for a while, and I'll admit I don't always follow perfect sleep hygiene. But there is something about dumping my thoughts out loud that completely shuts down the repetitive, circular thinking that usually keeps me awake.
