NS-RED is not, strictly speaking, an eating disorder. It is thought to be a type of sleep disorder in which people eat while seeming to be sound asleep.
They may eat in bed or roam through the house and prowl the kitchen.
When people with NS-RED awake and discover the evidence of their nighttime forays, they are embarrassed, ashamed, and afraid they may be losing their minds.
Some, when confronted with the evidence by family members, deny that they were the perpetrators.
They truly do not believe they could have done such a thing and cannot admit to such dramatic loss of control.

Isn't it so surprising?
