drowsiness
Pre-slumber mental fog
Drowsiness is the state of being sleepy or half-asleep—that heavy-lidded feeling when alertness fades.
It suggests a pull toward sleep rather than full wakefulness: The medication's side effects include drowsiness.
Warning labels caution against operating machinery if drowsiness occurs.
The word implies a gentle, gradual onset rather than sudden exhaustion.
