How much alcohol do you drink to get drunk?

I just drank 3 10% beers, pirate water, and I’m only slightly buzzed. I am 6’ 180lbs and 20 years old, I don’t drink to often but when I do I can drink a lot. If I try really hard with the right things not to puke, I can drink a full bottle (1.75oz) 55% whiskey and not even be incomprehensible. I can still think and do most things I want to. When I drink I’m mostly on the couch watching tv. Is it just me or do I just have a high resting tolerance?
