Interestingly, the Hebrew word for feast, mishteh, implies drinking...lots of drinking, admittedly, usually in a negative sense (as it is repeatedly used in Esther 1), but not always.
I kind of like Psalm 104:15, "[You cause] wine to gladden the heart of man." In other words, a bit of a buzz is a gift from God.
Have you every attend a Jewish Passover Seder?
Ya got to get through four cups of wine to complete it.
That's a bit much for me.
