Still, this isn't enough to diagnose you. Excessive daytime sleepiness could simply mean you're not getting enough uninterrupted quality sleep due to another reason, like stress, noise, or sleep apnea. Once paired with another symptom of narcolepsy, however, the likelihood goes up. Narcoleptics often experience one or more of these symptoms, which seem to get worse over time:
- Nightmares or very real hallucinations as your about to fall asleep or wake up.
- The sudden loss of muscle tone, which can be subtle or cause you to fall (called cataplexy).
- Feeling like you can't move at all—like you're paralyzed—just before sleeping or as you're waking up.
