At work for me it is no more than two cups of coffee in a day supplemented by copious amounts from the water cooler, and my wife sups very similar.
On an evening if we both finish after 5pm or so we usually eat at a restaurant on the way home and that meal usually is accompanied by a glass of red wine.
On an evening at home, it is usually a glass of Soda Water. However, if we do feel we deserve something stronger, Carol enjoys a white wine and Soda, while I enjoy a glass of soft red usually of the brand "Blossom Hill."
However, on a weekend or when we have had a really good day at the office, I will push the boat out with a nip of the liqueur "Cointreau" aided with a dash of Brandy, just gorgeous.
On really special occasions my favourite of all drinks is the Liquor Drambuie mixed with a nice splash of soda water. Again gorgeous but at £25 for a small bottle somewhat expensive, so I often refuse to buy that just on a point of principle.
For weekends and special occasions Carol my wife enjoys a glass of special reserve Port.
