I agree many of us make it over complicated but I also think most of us need at least some kind of support to remind us of the dangers.
Some here think that groups like AA and talking about drinking twice a day help them stay sober. That would make me think too much about alcohol when I want to do the opposite and think about it less. That said, I wouldn't be sober today if it were not for my wife nagging me over and over and me finally going to psychologist who kept me accountable.
I don't think I could do this alone, I would have a beer in my hand right now. Yet, I don't overthink the drink and then I won't sink.
