why cant i get drunk?

please feel free to delete if this isnt the right place but idk what else to do 😭

im 19, have drank now about 3 times and at one point had six shots of jack daniels (40% alc volume) and have felt Nothing. maybe some hunger, but thats about it.

im 220 pounds, so i know it would take more alcohol for me to feel anything, and my family is full of alcoholics. but come on now, second time drinking and having six shots? shouldve felt something.
