If you’ve had enough that you start making bad decisions, at whatever that point is, you’ve had enough. If you’ve had enough that you don’t later remember making said decisions, at whatever that point was, you’ve definitely had enough. If you want Biblical examples, there’s Noah getting “get-nekked” drunk, and Lot having his daughters get him “have sex with us” drunk, and several passages in Proverbs. They’re not talking about just relaxing and having a good time with friends and family. They’re talking about getting messed up.
My decisions got so much better while drinking booze that I was never wrong...I also became an excellent driver...
