Randomly cant seem to drink alcohol without feeling weird

i (25 F) all of a sudden react weird to alcohol. i used to drink 2-3 days a week. nothing crazy. alcohol would make me feel more social and i wouldn’t drink a lot so i was never hungover. it just made my time going out or watching a sporting event more enjoyable. i didnt need it though.

randomly, whenever i drink now i feel pukey and wired the next day. no matter what the alcohol is; vodka, tequila, wine, i feel the same. it’s like i have one drink and need to throw it up, but i don’t throw up. then the next morning, i feel like i’m on speed. thinking super fast, racing heart, and repeating songs in my head over and over again to the point where it feels like i’m going insane. i am also completely hungover and feel like i got hit by a bus. i did start taking those purple pills though before drinking and haven’t been hungover since then so i think that was just a dehydration factor.

long story short, i used to react normally to alcohol. now it’s like my body wants nothing to do with it and it makes me feel like i’m on speed or crack the next day.

EDIT: okay i’ve never actually don’t speed / crack im just using a comparison to what i think it would feel like.

i would have no issue completely quitting alcohol but i don’t want to… i’m young and enjoy a drink or two. anyone know what in the world is going on with me?
