Excessive Sleepiness
Excessive sleepiness is caused by a shift or disruption in the sleep/wake cycle, whether from lifestyle (shift work, use of alcohol or sedatives) or a sleep disorder (Obstructive Sleep Apnea, Insomnia, Narcolepsy). Excessive sleepiness can significantly affect your quality of life and causes a multitude of issues such as:
Difficulty concentrating
Physical fatigue
Memory lapses
Irritability
Low energy
Sometimes this symptom can be overcome through behavioral changes, but individuals experiencing excessive sleepiness may be suffering from a sleep disorder.
