Buy yourself a white noise machine. I’ve been using one for almost 10 years, it’s helped my sleep routine immensely. I prefer it to something with talking because the fluctuations of something like comedy would disrupt me. Also, I think that concentrating on something like comedy makes me want to watch it and I would woke up.
The next thing is an eye mask. Even if your room is mostly dark, I’ve found it helps me to stay asleep.
