Does narcolepsy happen every night?

Narcolepsy is a long-term nerve disorder that makes it hard for the brain to control when you sleep and wake up. It is usually marked by being too sleepy during the day, having sudden sleep attacks, and other sleep-related symptoms like cataplexy (muscle weakness caused by strong feelings). One thing that many people with narcolepsy wonder is if the condition affects them every night, especially because it makes it hard for them to sleep. This question doesn't have an easy answer because narcolepsy affects people in different ways and the symptoms can change from night to night.
