I knew an extremely functional alcoholic like that once. Dude was a beast with computers and coding but he would rip through two to three Natty Daddy’s a night. Super smart but I just can’t believe he can consume so much every night and function like a normal human being the next day. Apparently he would write and fix code while drinking. Kind of seems like a recipe for disaster but sure enough, he gets it done and done right.
I tried what he did once and nursed a hangover for the better part of a day.
