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.

Famous quotes containing the words excessive and/or daytime:
“As nature requires whirlwinds and cyclones to release its excessive force in a violent revolt against its own existence, so the spirit requires a demonic human being from time to time whose excessive strength rebels against the community of thought and the monotony of morality ... only by looking at those beyond its limits does humanity come to know its own utmost limits.”
—Stefan Zweig (18811942)
“This was your place of birth, this daytime palace,
This miracle of glass....”
—Philip Larkin (1922–1986)
