How am I such a tank

To be clear, I am a 6ft 3 170 pound man. So though I am tall, I’m not necessarily large muscle wise or chubby. I also don’t drink often either. I drink about once a week (when I go out) and normally have enough to be mildly drunk (4-5 drinks). So I am not an alcoholic and I’m not large.

Last night I went out with my friends. Before going to my friends place I had 8 shots of Tito’s from a double shot glass with no chaser (4 double shots). I then went to my friends place and had 4 shots of fireball from a shot glass and 3 homemade (but potent) Jell-O shots and a shot of Malibu. Then we left to go to the club. We always pregame a lot before because of drink prices these days. I want to make it clear that the time duration when I took my first sip to when we left was probably 2 hours. So before going out I had 16 drinks. And I was drunk certainly, but I felt fine. I didn’t feel like I was gonna get sick and I didn’t blackout and I wasn’t even stumbling or slurring words.

We went out and I had two coronas. Within the first hour of arriving. So in a 3-4 hour span of time I had 18 drinks. I wasn’t sloshed but I took an Uber back home, drank some water and went to bed. I woke up completely fine (but had a slight dry throat but after drinking water I felt fine). I woke up at a good time completely healthy and went to work and remember everything last night bright as day. So my question is, why? Why wasn’t I fucked up in the morning? Not that I’m mad about this I’m just confused why I can drink so much and nothing happened to me negatively health wise. Not that I’m complaining lol.
