Replace your "doomscrolling before bed" habit with something that doesn't involve screens or something that has a definitive ending so that you can actually go to bed once it ends. I replaced it with reading comic books and it's been working very well. Watching a movie also kinda works. The goal is to get in the habit of doing it, and resisting the temptation to doomscroll.
