Idiopathic Hypersomnia and Narcolepsy: Similarities and Differences 

Very informative

I can regularly sleep 12-16 sometimes even 18 hours. Often. I can sleep for 12 hours and STILL fall asleep during the day. I can sleep 15 hours and not feel like i slept too long and feel normally rested. Other days, i only get maybe 5 or 6 hours of sleep and sometimes on those days I dont fall asleep at work and many other days Ill dose off 20-40 times throughout my shift. I work 1st shift so its not that.
