Strictly speaking, I'm not really an insomniac - I'm nocturnal, a creature of the night. Kinda like Batman, except without the abs... and the punching.
Not to be confused with NoKTuRNL, an Ozzie rap metal band, or Knoc-turn'al, a US rapper-songwriter, or even Nokturnal Mortum, a Ukraine black metal band.
I'm using the word strictly in the adjective sense... with a bit of Batman thrown in.
Everything is better with a bit of Batman thrown in.
