looking for advice on my low alcohol tolerance

i (18 f) am about to go to a party where there will be alcohol! wow!

my problem is that i’ve only had alcohol a few times in my life, a few years ago when i was with the wrong crowd i went to a party, had 3 vodka cruisers within half an hour and threw it all up.

so i thought to myself id try to see what my tolerance was like…

took a shot of vodka every 30 minutes with a glass of water to follow and threw up for hours after the third shot.

now two years later i want to have fun at this party but im worried ill ruin it for myself and everyone by throwing up everywhere again.

i’m fairly light for my height (167cm and 51kg) so this could play a part i suppose, along with my age at the time.

my game plan is to really space my drinks out and have lots of water in between, along with a full stomach throughout the day. does anyone have any advice or similar scenarios? i don’t want to accept the fact my tolerance is low because i want to drink like i see everyone around me doing, but i fear it’s the root cause hahaha. thanks for any advice!
