i didn't drink until i was 22. it's kind of nice to see other infjs embody the same opinions as me, when, at the time, it seemed like i was socially insane.
i drink wine, beer, and whiskey a few times a week. i have a lower threshhold of desired drunkenness than say my entp friends, but an occasional drunk can do one some good. it's like a hard reboot. sometimes it's the most effective and easy way of getting the clutter out and starting fresh. it doesn't solve your problems or address them, but it provides a temporary relief at times. life needs this, especially when we do it together as a social ritual to blow off some steam and admit we don't know or have all the answers or are able to fix all the broken pieces in our lives.
plus it helps dull an overly sensitive sharp biting edge that i can sometimes take on. i am a much better person, socially speaking, when i take the edge off every now and then. i lose some of my rigid inflexible idealism and have a much easier time going with it, getting in the moment, etc. often i get gushy like an enfp and all that matters is a good meal and everything is rosy cheeked and merry and bright. hell- i have enough idealism to spare some time for some friendliness, every now and again, and the ability to assert myself as is more freely is very helpful, fosters openness and expressiveness which is unquestionably good (if you want to actually connect with anything, extravert, meet the world and the people in it halfway).
just bc most of the people you see drunk and saturday night staggering are people who don't share your values, or are painfully un-N, or are downright terrible drunken assholes on a streetcorner doesn't really mean that alcohol is to blame. the use and abuse of alcohol in life is a question that is rooted in many other social and psychological issues.
