The main thing that sorted out my sleep routine was fixing how I wake up. In the end that helped me fall asleep in the evenings. I have one of those Lumie wake up light and radio alarm clocks. From about half an hour before the set time it gets progressively brighter. Them at the set time the radio comes on (BBC Radio 4 in my case). Then a few minutes later my echo alarm goes off, by which time I'm already awake, woken gently by the light and sound. You could go the IoT route and have you main room light slowly brighten and play podcasts or radio streams. In the early days I had an electro mechanical alarm clock that did the job of the echo. I put it the other side of the room so I had to get up to turn it off. For getting to sleep I realised I needed something to distract my brain so I have a speaker pillow. I plug my phone in and listen to podcasts. I use podcasts that are kind of interesting but which I don't care if I fall asleep to. It's enough to giv my brain something to keep it a little busy without actually being stimulating enoug to keep me awake. The other thing is to stick to your routine most of the time. However it's also entirely possible that you are naturally a night owl. Chronotypes are a well established idea.
