Twilight Zone of Sleep Deprivation 

The experience one gets at a certain point of energized exhaustion. When the body is starting to shut-down due to late-night/early morning hours, but is being forced to function through a surplus of caffeine intake at regular intervals.

Anyone currently in the Zone will feel the symptoms of weariness coupled with jitteriness, loopiness, possible dizziness, and a distinct feeling of being overwhelmed by whatever it is you are trying to stay awake for. S

pelling as well as communicating will most likely become difficult as well as thinking in general.
