<unk>  is an eating disorder that has only been recognized as such since 1999, and affects between 1 and 2% of the population. <unk>  is also characterized as a sleeping disorder. <unk>  is often accompanied by or confused with sleep-related eating disorder (SRED), although the two are distinct.
This is an ongoing, persistent behavior, unlike the occasional late snack or skipped meal that most people have from time to time.  In fact, people with this disorder are often unaware of their nocturnal meals, although some feel they won't be able to sleep without eating first.  ( Note:  a person falls asleep more easily on a full stomach. )  Among those who are aware of their<unk>  eating, there is often an emotional component;  the diet of the<unk>  eater is comfort food.
