Uhhh Sunday is the Lord's day you shouldn't be drinking.
Technically, everyday is the Lord's day since he created them all, but if you mean the day of rest also known as the sabbath day - that would actually be saturday. Don't forget, sunday is the first day of the week and the first 1000 years on earth (or the first day in heaven) that the sun was formed, hence the name "
sunday"
OP, feeling hungover at all today?
