The trick I've learned with alcohol is to finish a whole bottle or else you will wake up in the middle of the night

If you finish half a bottle of whiskey or gin or vodka you will wake up between 2-4am and won't be able to fall back asleep. Whereas if you finish the whole bottle you will get a good night's sleep and wake up at 8 like a regular functioning human. Always finish your bottles of alcohol.
