I didn't sleep
Io non ho dormito per nulla la scorsa notte.
I didn’t sleep at all last night.
Non ho dormito bene la notte scorsa.
I didn't sleep well last night.
I didn't sleep on the plane.
Non ho dormito pensando a tuo figlio.
I couldn't sleep thinking about your son.
— Tutto su mia madre (1999)
I didn't get enough sleep.
Il cane ha abbaiato tutta la notte e non ho dormito.
The dog barked all night and I didn't sleep.
