NON-RHYTMATIC SOUNDS DRIVE ME CRAZY.?

It's effing 1 in the morning and I am PISSED because I can't effing sleep! Damn sounds that don't follow a rhythm make me insane. My box fan keeps clicking weird intervals and I have already spent 20 damn minutes trying to pick every effing piece of hair or crap out of it. IT STILL CLICKS and the dumb dog keeps randomly scratching itself. I am going mad. What should I do, down some NyQuil? Yes?
