They sound like functioning alcoholics. It'll take one BIG, bad event to shake them out of it. When they've lost everything they'll wake up and get help. Usually it's AA.

You really can't do anything. It has to come from them.

Vowel Lady, I am in remission from psychological (not physical) alcohol addiction.

What you have described about your friends is very familiar to me.

As Wiix wrote, the choice must be theirs - I think that all that you (as a friend) can do is to support them in their choices.

Hi Vowel Lady,

I agree with Wiix and Kiwi to a point, but his behaviour - loud and inappropriate - is obviously affecting you. As had been said, most alcoholics lose everything, including friends and family, before seeking help. You can choose to be part of that pattern and distance yourself from them, thus sparing yourself the pain of seeing friends deteriorate - it seems inevitable anyway.

Or you can tell them, kindly and calmly, how his inappropriate behaviour makes you feel and you cannot tolerate it. Either they will realise their actions have consequences and it may be the first step they need/choose to change, they will moderate their behaviour around you or they will dismiss your feelings - in which case they are no friends at all.

Having been both sides of the bottle many times with many people, and finding myself there again, I know how difficult it is to deal with alcoholics. Just keep a calm head whatever you decide.

Dave.
