You might be suffering from hypersomnia. It may present as excessive daytime sleepiness or nocturnal sleep of long duration (as much as 12 h or more) or sleep drunkenness.
Patients do not get abnormal amounts of night sleep rather they have problems waking up in the morning and staying awake during the day. Hypersomnia is sometimes misdiagnosed as narcolepsy where a person experiences a sudden onset of sleepiness. The causes can be genetic, brain damage or medical disorders such as clinical depression, uremia and fibromyalgia. Sometimes hypersomnia may be other sleep disorders such as narcolepsy, sleep apnea, and restless leg syndrome. Your symptoms may be linked to depression.
You should consult a psychologist for a complete medical and psychological workup.
