What does excessive daytime sleepiness (EDS) look like?

ANSWER

People with EDS feel so drowsy during the day that they’ll typically fall asleep during the day if they’re in a boring or sedentary situation. They might fall asleep while stopped at a stoplight or sitting in a waiting room. EDS is usually caused by conditions like sleep apnea, restless leg syndrome, narcolepsy, neurologic conditions such as Parkinson's disease, as well as many medications.
