New drinker here, why cant I get as drunk as I was a week ago?

About a week ago, I got absolutely shitfaced, I had about 5 shots (straight) and a beer, that got me to the point where I couldn’t walk straight, I was crying with my dog (well she wasnt crying she wanted to punch me and go to sleep but nah drunk me sat there for half an hour crying and saying I love you waffs I promise I’ll take you on more walks.. Lmaooooooo I fell over while putting my pj’s on and my dad came in my room, me being buckass naked I slammed the door and I didn’t even realise I existed until after I slammed the door. Lol. Shit was fun But it was my first time getting drunk, well couple months ago I got a good high off a few beers but no where near this level.

And now, ive tried to get as drunk as i was that night because it felt awesome and I cant seem to do so.. I mean ive just drank a third of a bottle of 35% 700ml spiced rum and im just sort of out of it a bit. Feel a bit tingly and talking to myself about dumb shit but not shitface level.. Ive tried 3 times in like the last 7 days and aaaaaaghhh

Help man I wanna get shitfaced again. Pls
