why is my tolerance so inconsistent?

ill preface with the fact that i’ve got an extremely high metabolism. it’s just my uneducated guess that this may play a factor behind my tolerance being so whack.

but from everyone that i’ve asked, most people don’t get any noticeable feeling off of 1 beer. when i have one pint or even just a can, i seem to get a noticeable physical feeling of being tipsy. it’s not like im drunk or super tipsy, but enough for it to affect my balance to stumble a little more and be generally more clumsy.

it seems to last shorter than what’s common, but be much more intense. my guess is that maybe im digesting it all super fast so its more noticeable and shorter lived.

what i don’t get, is that if i drink a spirit, ill have a higher tolerance than most of the people im drinking with. i don’t drink a lot, but when i started drinking it was on nights out and we never really had beer or anything, we always got vodka or tequila, i started like 16 and would drink every now and then with friends, and i would always be one of the ones to have the most shots.

anyone know why this is? im really curious why one beer can have such a significant effect on me but i also have a higher tolerance than most people around me when drinking spirits.
