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.

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?

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.

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