I’d like some trick to get my body onto a 24-hour cycle instead of a 25-hour cycle. I only have trouble getting up in the morning because I had trouble getting to sleep the night before. If Earth had a 25-hour day, I could go to sleep when I was tired, and get up when I wasn’t.
I don’t know. Maybe—light is the most important zeitgeber. Incidentally, it looks like the natural circadian rhythm for hormones and core temperature is 24 hours and 11 minutes, not 25 hours.
I doubt it’s the circadian rhythm that’s messing you up as much as it is the indoor light. Indoor lights are strong enough to affect cycle, and it is a common suggestion of sleep doctors to spend a half an hour with low light before going to sleep.

Have you tried melatonin?
Spend some time in the morning out in the sun or looking at a bright light. It resets the circadian rhythms.
Should I also sit in the dark before bed?

Yes. Or you can sit in a lit room wearing Blue Blockers.
