Maybe a good start could be not giving your brain what it wants, when it starts getting that active. Just let yourself become bored.
And if possible, get outside, walk, run, hike, enjoy nature, build something with your hands, get TIRED.
Reduce blue light and if possible remove any screens past 7-8pm (books, podcasts and audiobooks help a lot here!).
In the morning, get as much sunlight as possible.
Do not stress over your current schedule too much. Try to wake up early in the morning for a few consecutive days, even if you do not go to bed early enough. After some time, your body might adjust again to a normal rhythm.
