This insanity inducing phenomenon which keeps me fatigued and unnaturally active via a sadistic fraternization, could be any of the following: (bah!! what!? lack of sleep makes me say these things…)

1. Delayed sleep-phase syndrome where it is common for people to fall asleep after midnight, sleep soundly, and then have trouble waking up in the morning. They won’t feel drowsy if they are able to keep to their sleeping routine (ie. 4am to Noon.)
C. This is not me, because I will stay up till 4am, go to sleep, then wake up naturally at 7am very, very tired all day. (And I don’t nap.)

2. Obstructive sleep apnea which is characterised by pauses in the breathing during sleep. The sleeping individual is unlikely to be aware of this, but indicators are loud snoring, restless sleep, and sleepiness during the day. If this is you, in a worst case scenario you will develop a severe form of congestive heart failure called corpulmonale.
C. I am thankful that I do not have this.

3. Insomnia means you have difficulty falling asleep and staying asleep. Consequently you wake up grumpy and will experience functional impairment when attempting trivial tasks, such as typing an email – ir ceoemes veru diffiecult.
C. Yes. But not so much “difficult” as “I jist cannae be bothered.”

4. Nocturnal polyuria is when you get up to pee, all night long – very disturbing to sleep.
C. Not my problem. Surely this only happens to bad people?

This is by no means a thoroughly explained or exhaustive list, but what I was looking for was evidence – cited or claimed – that sleep deprivation can kill you, and I did not come across any, so that is good.
