You have to put some distance between you and drinking before you see it clearly. It’s like those hill figures in the British countryside. When you’re next to one, all you can see is the white of the chalk: you’re too close to see what it is. It’s only once you’re airborne or at a distance that ‘ohhhh’, the horse appears. Similarly, you can only see the full picture of alcohol, once it’s a silhouette in the distance.
