When I was younger, and worked 2nd shift 4-midnight, I would always have two beers and a shot of Wild Turkey, with two cheeseburgers for "lunch" around 7:30pm. If I tried that now there is no way I could go back to work.
Nowadays, if I'm at home I'll have a nice glass or two of high end Burgundy with lunch, followed by a brief nap. If I'm at a business lunch we may have wine, but always followed by an espresso and no nap.
