I've noticed I get more hungover as I get older. When I was in college (and underage) I could drink til I was a human pinball walking down down a hallway (which is only about 3 drinks cuz of my size)... and be up in action without a second thought the next morning.
Now, I have a drink and a half and I feel like I was eating chalk all night for a whole day... what's up with THAT?
And to all: start chugging water about halfway through the night.. it will prevent much of the eating-chalk hangover feeling caused by dehydration. Just don't use sugary drinks like gatorade to replenish - the added sugar will just make you feel worse
