Eat ~100mg of caffeine really quickly (like a caffeine pill or slamming some coffee maybe) and immediately set a 20 min to 45 min timer and get into bed. Fall asleep and depending on your condition you will feel mildly to very refreshed after you wake up. You'll probably be up even before your timer goes off if it's on the longer side.
I used to do the opposite. I'd slam a litre of sugary beverage, wait for it to pass through my tiny bladder and then go to bed and let the come down from the sugar rush push me into a sugar coma. Really stupid thing to do for a guy who has type 2 diabetes in his family.
