Ouch, this is clearly meant to be (at least somewhat) tongue-in-cheek. Calling it "drug abuse" is a little extreme unless you're familiar personally with the author.

It doesn't seem like it's affecting his life in an incredibly detrimental way, supposing that at some point when the hoopla of a book release dies down he stops drinking every night (and even then, the quantity consumed is an incredibly important component).

It's just jokes.
