Getting the mental slowing effect of alcohol, without actually consuming alcohol?

Are there any other ways to achieve the mental dulling without actually consuming alcohol? I know it sounds absolutely dumb but I am a big fan of fighting video games & for some reason I play better while intoxicated compared to sober, I can just dial in on the game. I’ve been cutting back on drinking but man it blows ass when I go to play for a while, sober, & get reamed but after making a couple cocktails I just start playing 2x better

I’d rather not have alcohol as the crutch to win an online or local tournament lol

edit i know this is picky but unless it’s something that can be sold over the counter, don’t rec please, i am not willing to illegally buy drugs or lie for a prescription lmfao
