Sometimes between 25 and 40, you'll realize you "can't drink like you used to."
From here, you'll almost never be out til last call again. Certainly not without regrets. And it'll dwindle to where you're learning to cook instead of asking the Uber driver to swing through McDonald's on the way home.
You'll find you're amid a new hobby, and an old hobby is in the rearview.
Welcome to midlife. You're probably as old as your parents were when they had you, if not older.
