Fall asleep exactly when you want every night, or 200k right now?
No more nights laying awake or wasted time with a racing mind.
Technically you could also drink caffeine right up until bedtime also.
What would you pick?
EDIT: you can choose when to fall asleep once per day, and have to use normal methods to wake up
So you could use it to take a quick nap during the day, then fall asleep naturally at night
