I've never had a hangover despite drinking for nearly a year now. A few days ago I got blackout drunk, throwing up, falling over, blurry vision etc. I woke up and felt slightly nauseous, which then faded away after an hour or two, and then I felt absolutely fine for the rest of the day, except maybe a little tired.
Both of the friends I was with drank less than me but were violently hungover the next day. Am I just immune to hangovers or something?
