I do not allow him entry when there are visible signs that he has been drinking. I also tell him that I am phoning (doing it in front of him) the traffic police and police and then he speeds off. In this country any abuse (drunk visits count as abuse) against women and children is highly frowned upon. Unfortunately people do not have knowledge/ make use of this .
It might be dangerous for other people to do as it can lead to violence. As of lately my husband is scared of me due to me not backing off ever. He does not pitch when he drinks.
I document all the drunk appearances and the not pitching. he is welcome to visit when sober.
