liquor question

hi everyone, i hope you’re all well i’m 21 yo, 6”1’ at around 260-265 body weight, have been consistently drinking for about a year or so, i normally have about 1.5-2 bottles of wine to get to a decent buzz/happy level. i am aware my tolerance has build up however today i decided to try stronger alcohol in a very long while, i got a 38% sambuca 70cl bottle, i had over half of it within 30 mins on a very empty stomach (haven’t been eating since yesterday) and after about 400ml of sambuca i thought i’d stop about 3 hours ago, however, i only feel slightly kind of tipsy, what i would normally feel after half a bottle of 12% wine, i was wondering why that is; considering all other experiences online it seems that most people would get hammered from this amount, thank you
