As someone who’s never drunk a full thing of it besides a beer once at around 18(?), I can say I have never gotten drunk before. I’ve also had some sips but definitely not drunk.
I want to try actually having some alcohol besides that beer since I’m drinking age in the United States (I’m 23). I decided I would order a daiquiri for dinner with my girlfriend.
(If this helps, I’m 135 pounds, 5’6, and female.)
Considering your mass and (presumed) low tolerance, I would estimate that you’d notice the effect, but without getting drunk. Slightly tipsy, maybe. This assumes that it’s mixed to standard drink strength.
Two is probably also OK. Three is pushing it.
I’d say if they’re a lightweight (literally and figuratively) then two should probably be the max, and if you want a third get a glass of water or two before you get that last drink.
I’m a big guy, but I don’t drink much either and I’d definitely be buzzed after two drinks.
Full on tipsy, not slightly
