hello i kind of need help

so basically me and my girlfriend are 19, we barley drink ( like once every 3-7 months) but i do a little more than her. yesterday she decided to drink a beatbox (probably not the best choice) and today she’s been throwing up all day after getting pretty messed up off the one beat box yesterday. at first i was like im pretty sure it’s common for people to throw up in the morning after drinking, because i know i have, but now that it’s 6pm im getting a little worried because she’s still throwing up and feeling nauseated
