Depends on what I'm drinking. If it's irish whisky, bourbon or a nice, crisp lager I don't really change except to get louder than usual... Rum is my happy drink but I don't drink it any more thanks to a clapped out pancreas... pretty much everything else is off the menu because I turn into a mean drunk when I drink them.
Also, seeing as I can easily piss away $500 in a single night out on the booze, I also change from not broke to flat fucking broke. One particularly epic night me and one of my nephews pissed away around $1500 between the two of us... he's my fave drinking partner because he's an extroverted, happy drunk who doesn't put up with my shit if I get surly and, being a bit bigger than me and near half my age, can make his displeasure known if need be.
