* Everyone feels sleepy at times. However, when sleepiness interferes with daily routines
and activities, or reduces the ability to function, it is called “problem sleepiness.”
A person can be sleepy without realizing it.
A person may not feel sleepy during activities such as talking and listening to music at a party, but the same person can fall asleep while driving home afterward.
You may have problem sleepiness if you:
* consistently do not get enough sleep, or get poor quality sleep;
* fall asleep while driving;
* struggle to stay awake when inactive, such
as when watching television or reading;
* have difficulty paying attention or concentrating at work, school, or home;
* have performance problems at work or school;
* are often told by others that you are sleepy;
* have difficulty remembering;
* have slowed responses;
* have difficulty controlling your emotions;
or * must take naps on most days.
