It's not just the consumption and how it affects you. You also have to consider the effect of your alcohol consumption on others, especially your significant other, kids, family or friends. Maybe you're feeling fine with one bottle of wine every night, but I highly doubt your partner or kids feel the same way. You may not notice it (because your intoxicated, after all), but a bottle of wine does affect your behaviour. Forgetting things, repeating yourself, being annoyed more quickly, incoherent stories, some verbal aggression... all minor things you may not notice, but the people around you do. And they don't like it.
