How can I drink this much without getting wasted

Hey guys.

Maybe a weird post, but, I’m a 5’5, 26 year old lady and slightly overweight. I can however drink like there’s no tomorrow and not get incredibly drunk and get myself home (by bike, no worries – don’t drink and drive!) just fine. I’ve never even had a hangover. I do snack inbetween drinks, but I can easily drink two bottles of wine and a few beers.

If I see someone else drink one bottle of wine, they’re puking or just drunk out of their minds. I was wondering if anyone knows the science behind this, because people around me are baffled when they see me drink and I am honestly curious too 😂

Thank you!
