am I allergic to alcohol/intolerant or just really lightweight?

last night i took 2 shots of smirnoff raspberry and mixed it with some soda and i felt ok. then i felt a itching sensation across my entire body, mainly on my legs and hands and feet. my face got really red and my hands were a deep color red. i insisted i was fine but my friends were worried and said it wasnt normal and i got concerned so i decided to lay down and just sleep it off. my heart goes about 200 bpm as i try to sleep and my friend checks up on me an hour later and wakes me up from stasis and as i tell him how i feel he pushes me to the toilet and I say im fine i dont need to go and yet I projectile vomit all into the toilet. i vomited 5 times and shit came out of my nose and I started fuckin crying because i was worried about how much liquid came out

AITA?? i mean am i allergic? i always feel itchy every time i drink
