Unlike methanol, short-term excessive exposure to ethanol probably isn't going to screw you up permanently. Don't college students do this all the time, and still graduate?
Living in a college town, here's what I consider to be the most common signs of overexposure to Ethanol: Getting either vastly more "teddybear like", or vastly meaner and confrontational. Kinda depends on the underlying personality revealed when inhibitions are reduced.
One would seem to be less harmful than the other.
