Have you paid attention to what your thoughts are at night? I've had similar issues before and I've noticed that if I think about work, projects, my day, etc. I could go on for a long time without falling asleep. I began to notice that if I think about generally fiction/stories, I can fall asleep much more quickly. In my case I think about plots of movies I've recently watched (or a long time ago), whether it's Avengers or Dragon Ball etc. Perhaps you could give that a try.
