drowsy

I was told that to keep the people awake a man sometimes goes around spurting cold water over the drowsy and nodding heads.

He raised himself amongst the down pillows, and contemplated the figures upon the tapestry in a drowsy reverie.

At intervals throughout the car, drowsy heads bobbed up, the glances of their owners sleepily directed toward the rear door.

To add to the peril at any moment, either the drowsy man by the fire, or one of the sleeping men beyond, might awaken.
