Hi, I'm A 21 Year Old Female And Have Been

hi, i'm a 21 year old female and have been drinking hard alcohol pretty much every night for the past 5 years. i drink a lot, sometimes 20-30 shots, in a night. i usually don't get hangovers and when i do, i just have nausea until i eat and drink something. if i throw up from a hangover i feel better instantly. last night i only drank about 10 shots over a long period of time and when i woke up the next day i had horrible nausea and threw up many times throughout the whole day. could my body be making a resistance against alcohol or something like that? this was not normal at all.
