I would take melatonin or another sleep aid at the time you intend to be going to bed (presumably some time in the morning) over a period of days to help force you to sleep during the day, so that you will be unable to fall back asleep at night.

You can also take Sudafed, caffeine pills, or any other stimulants in the evenings to stay awake through the night.

I know it sounds like I'm only suggesting drugs, but that's because I'm only suggesting drugs. 😶

Best of luck!
