There's no silver bullet for a last minute, "Damn, this whole sleep thing isn't working", so plan ahead. Your body has an internal clock that reacts incredibly strongly to food and exercise. It's quite simple really. You don't need a lot of exercise, just some basic movement throughout the day like walking or pushups/squats if you're feeling ambitious. Make that happen before dinner. And make sure that you don't eat too late, certainly avoid late snacking if you can. Plus, hydrate a lot. Drink water every hour or couple hours if you can. This should all be really easy, and the benefits compound over time. Other tips also work like avoiding caffeine/alcohol, but what I mentioned should be a general baseline. Habits that you should always do, especially because some of the other tips are hard to perform consistently.
