"Nocturnalism"... is that even a word?
Well, if it isn't I just coined it. And if it already is, then bravo! I just expanded my vocabulary.
Anyway, I seem to have resorted once again to being a nocturnal insomniac. I was sooooo close to breaking the habit. And Bam! Next thing I know I find myself sleeping at the first sign of dawn and wondering where on earth my mornings went to.
