Heya Movingforward, I agree with everything that others are saying about boundaries.
Perhaps make a list but it is not to be shown to him. This list might have: if he starts drinking I will get a hotel room. Boundaries are what YOU will do given certain circumstances.
As we all know, engaging with drunks does not work. When you act on a boundary, it is probably best that you don't even tell him. Just do what you need to do to protect yourself.

This buddy actually offers a great example of a boundary. Drunk friend is not appropriate around kid so kid doesn't come over anymore. Well done to AH's buddy.
