Open for business

I can go for fortnight without a drink — three weeks at a push. After that I begin to feel disconnected. I try to ignore the feeling, hoping it’s a symptom of Seasonal Affective Disorder, or the onset of a cold, or overdoing it at the gym. But it persists and, after several days, changes into a consuming, impotent rage, at which point the penny drops and I know that it’s time for a drink.
