Very weird experience with alc

Hi! Had the weirdest experience with alcohol today and I was wondering if anyone has ever had anything similar.

I’m not big into drinking but tonight I had around 4 shots (2 whiskey, 2 vodka) within like an hour. I was feeling anything and suddenly it hit me like a truck. Everything is a big blank. My fiancé says I was switching moods like super super happy, and then not even 3 mins later start sobbing, then a couple secs later get very angry. It lasted about an hour and a half- then I threw up. About like 30 mins after I was TOTALLY sober. Never had this experience with alcohol before- almost felt like I was greening out.
