Enough for what exactly? A common pour of wine is 4 - 6 oz.

Also, I'm sorry you don't like alcohol, but not all use is abuse. I wouldn't even go as far as saying occasional and mild drunkenness itself is problematic.

I don't disagree that in many cases substance abuse happens because of external problems and unless those are fixed relapse becomes almost inevitable. Sometimes that has nothing to do with connecting to others; there is a reason the opioid crisis is hitting rural areas that have been hit very hard economically.
