There is a number of sleep disorders that often would have one symptom in common, and this symptom is known as excessive sleepiness. Symptom like this one is very dangerous, even though it sounds harmless.
Excessive sleepiness is not something that will easily go away, if you have some rest or a proper good night sleep.
It will last until the actual cause is found and treatment is prescribed. When it comes to disorders like:
- obstructive sleep apnea
- or shift work sleep disorder
This is the one if not the most persistent symptom and also the most common one.
Often doctors would prescribe Provigil, a medicine that belongs to a group of stimulants, promoting wakefulness, repairing the broken sleep and wake cycle, telling the body when it needs to fall asleep and when to stay awake.
