Sleep, Actually
Narcolepsy in plain English
A long-term neurological sleep disorder that affects how reliably the brain holds the boundary between sleep and wake.
Narcolepsy is a long-term neurological disorder that affects the brain's control of sleep and wakefulness. NINDS describes it as a chronic condition in which people feel overwhelmingly sleepy during the day, whatever they did the night before.
The clearest way to hold it: the switch between sleeping and being awake does not stay put. Pieces of sleep can arrive during the day, and wakefulness can interrupt the night.
It is lifelong, it is not caused by laziness or poor discipline, and it is diagnosed by a qualified clinician using sleep testing — never by a website, an app, or a wearable.

Sleepiness versus ordinary tiredness
Tiredness is low fuel. Sleepiness is pressure to fall asleep. They feel different and respond differently.
