You have a tuff situation and
you have to be tuff. Oxy w/booze can kill depending on amounts he drinks the combo can cause respitory arrest (stops breathing} I' ve been there got me off oxy's at least anything above 10
mg, saw 80' plus. if he does not drink much thats a plus. You are right it could ruin you finacially the move out could help him see the light but talk to him he has to want to quit you can't make him quit.
