Is alcohol overrated? No. Is getting drunk overrated? Sure.
There's known benefits to people have a few drinks, people can loosen up and have a good time, easier to meet new people, a few beers with some friends goes down well, having wine with dinner is great depending on what you have…
Getting drunk though… you act irresponsibly, you make a fool of yourself, you make a mess, others can get caught up, your actions can have severe consequences, bad for your health, you wake up with a hangover… etc.
I see nothing overrated in having a few pints with some friends, having some wine with my pasta
