Mine got so bad I was blacking out a couple times every week. Led to a couple embarrassing incidents my family had to bear witness to. Nothing serious, but taking a blackout whizz where you think there ought to be a toilet is pretty embarrassing... the next day hearing about it... Also did this weird blackout thing of completely unhooking and disconnecting my PC/monitor/mouse/kb and shoving it all into the corner of the room. Why? I dunno. Just did.
