Excessive daytime sleepiness (EDS) is characterized by persistent sleepiness, and often a general lack of energy, even after apparently adequate night time sleep. EDS is a symptom of sleep disorder hypersomnia, another symptom being prolonged nighttime sleep.
Some persons with EDS, including those with narcolepsy, are compelled to nap repeatedly during the day; fighting off increasingly strong urges to sleep during inappropriate times such as while driving, while at work, during a meal, or in conversations. As the compulsion to sleep intensifies, the ability to complete tasks sharply diminishes, often mimicking the appearance of intoxication.
