how to sober up?

hey guys, ive usually only smoked in hs, only drank a few times, and just went to a college party for the first time. basically did a ton of shots and smoked weed. i woke up with no headache, thinking oh wow no hangover. i thought a hangover was just a headache or feeling sick.

i think i might be hungover? i feel fine but im acting soooo goofy. my dog attacked my neighbor and i just stood there and laughed at him and then proceeded to stare at him until he left. my dads chewing with his mouth open is driving me so much more up a wall than usual. i just feel not sober. i have like four hours before i need to go to something, what should i do lol
