When I was still drinking, it left me open to the kinds of interactions with men that I wasn't really looking for. Being open to drinking on a date made it harder for me to enforce my boundaries and easier to get into a situation where inhibitions were low and casual sex was likely, and It allowed me to keep the interest of men who saw drinking as a pastime, where I think probably those same men would now think me a bore. I don't miss them one bit.
Have you ever considered adding a booze ban to your man ban?
