does playing poker sober actually make you more money

always heard ppl say you play smarter poker if you stay totally sober, but honestly i'm not sure. i know for blackjack or roulette you want your head clear, but poker’s so social, and sometimes i feel a beer or two actually helps keep the nerves down and makes you a bit harder to read. not talking about going overboard, just like… smoother vibe, and you don’t get wound up after a bad beat as much.

most of my live sessions are in the smaller stakes rooms and i see a lot of regs nursing drinks, but also a few who stick to water and always seem serious. thing is, i can't tell who’s winning more long-term, and my own results are all over the place. wondering if anyone’s tracked their sessions on this, like is it really worth making a rule about it, or just keep it flexible based on how you feel that night.
