In order to be able to fall asleep on the flight I normally sleep a little less the night before.

I assume you are taking CX from JFK or CO from EWR, both of which have flights at that time. Both airlines have AVOD (I'm partial to CX here in saying CX is better, but IIRC CO's wasn't too bad either), so that should make the passing of time much easier.
