Am I completely out of line?

No.

it was so out of control previously (like extremely drunk almost every weekend, out until whatever time in the morning with friends) ... So I constantly got on him about not wanting him to drink and got on him about being gone till the wee hours when he goes out and now I’m the nagging “not fun” wife

Yeah, he needs to grow up.

Constantly getting on him, unfortunately, encourages him to see himself as a rebellious child, and is probably counter productive.
