why did I throw up? beginner or poisoning?

hi all! i (f20) drank hard liquor for the first time in my life. i usually drink white claws and all the fruity sweet drinks. never have i had hard alcohol.

i went over to a friends and had about 5 shots from my memory. i eventually got drunk and felt great but eventually felt like shit and started throwing up outside (like a lot). i threw up on the car ride home as well.

i’m weirdly not crazy hungover but my head hurts from how much fluid i lost and the dehydration. i rarely drink like this let alone get drunk.

did I throw up because of being new to alcohol and couldn’t handle my share? do most ppl throw up from 5 shots? is that considered a lot? or did i throw up from alcohol poisoning?

any advice works! i’m a bit new to stuff so anything will help 🙂
