The last time I was able to keep these hours regularly, sitting at the keyboard at 1 am with a couple of hours work ahead of me, was many, many years ago. I used to take screen breaks every hour or so – I’d go out for a cigarette, take a walk, refresh myself, and then come back to work. I used to love walking up and down the road in the quiet at the dead of night, smoking and thinking. God, but I really, really want a cigarette right now.

Instead, I shall pour myself a whiskey, and get back to it.
