Naturally low tolerance for alcohol?

So i am not a hard drinker, but when I do drink, I take gin, vodka, tequilla dry shots, or chased. And it happens every other weekend for probably a night or two.

So I dont know if this is alot.. Outside of that I never drink. Last weekend I went hard, deunk from Friday night to Sunday evening, and then there after had a gnawing pain on my right rib.. Painful when I dont touch and also when I do touch..

I fasted and its mostly gone now but I’ve had this pain once before, exact same location, after a weekend of drinking.

It seems like my liver is already comolaining when I really dont do alot or even close to what some of my other friends do.. Could. It be possible that its just the alcohol or rather the alcohol affects my guts badly?

Anyways im not posting for medical advise, jist kind of thinking out loud why my liver is acting like such a whiny btch lol.

Ps: decided to quit alcohol after that weekend
