hitting the sack

Retiring for night

Hitting the sack means going to bed or to sleep.

The phrase is informal and suggests retiring for the night, often with some eagerness: I'm exhausted—I'm hitting the sack.

The sack is the bed itself, probably from the straw-filled mattresses of earlier times.
