In the morning, individuals with night eating syndrome are not hungry and do not usually eat breakfast. These individuals do not binge during their night eating and seldom purge.

Episodes of apparent awakening from sleep, accompanied by signs of panic, followed by disorientation and amnesia for the incident. These occur during nonrapid eye movement sleep and so do not involve frightening dreams.

Millicent sits up in bed several times a week, shouting and crying as if she is terrified. Her mother takes her to the pediatrician who suggests that she is having night terrors.
