Lol. I keep a microfibrecloth close to me at all times to constantly wipe off any little irritating black spot I see on my monitor. Sometimes the spot I try to wipe off actually moves, then I need to throw my cloth away and go for guns instead..

And you also know you are addicted to AH when you don't just sit down infront of your pc to do a few sorties, but the whole login secuence becomes a 5 min ritual of carefully setting up chair, stick, sitting position, mouse location on the desk, coke/beer, cloth to wipe the monitor.. In short, do almost a checklist procedure for all the things u might need to stay focused to the game.
P.S. Don't forget to go to the toilet before logging in, you might end up behind enemy lines and taking a leak might get you captured..
