Probably not. Inadequate sleep can cause lots of symptoms: fatigue, irritability, headaches, memory and attention problems, increased accidents, etc. The symptoms resolve with adequate sleep. Narcolepsy is a chronic medical condition which is associated with excessive daytime sleepiness, sleep paralysis, vivid dreams, and sudden drop attacks associated with strong emotion. The epworth sleepiness scale can help.
Insuff sleep. Probably not. Insufficient sleep is the real problem. Naroclepsy is a problem with the brain and the sleep/wake turn on and off. This is not a problem that "gets better or changes day to day." insufficient sleep can make you feel terrible and last longer than 1-2 days after a bad night. The only way to solve is making more time for sleep.
