I don't drink much in the flat. Getting hammered alone feels a little sad and impairs my ability to insult people on here 
Generally, a nice dinner (gammon steak, egg and mash is a favourite) and a glass of Coke while the British card is on. Then I play some Xbox, come online, etc while eating crisps and sweets until the US card starts, by which point I move on to water until the US card is over. But more often I have a nap for a few hours so I'm not a wreck the next day for my other commitments.
