Here's the next series, which deals with waking up at night:
One: You did not wake up at night.
Two: You had a restless, light sleep with few brief awakenings each night.
Three: You woke up at least once a night, but you got back to sleep easily.
Four: You woke up more than once a night and stayed awake for 20 minutes or more, more than half the time.
(IF NEC: Which of these four statements was most true of you during your worst [(several days/two weeks)] of being [(sad/or/discouraged/or/uninterested in things)] in the past 12 months?
