I ended up on white wine pretty much all day at a sensible pace (aside from a beer when I arrived). What felt like non-stop eating for 10 hours probably saved me. Got home at 11pm and sat in front of the telly with a JD & Coke, started nodding off, went to bed.
Woke up this morning, scampered...
It'll start at about 1pm, and end at about Midnight... and it'll mainly be wine.
Got a lovely bottle of 2011 Gran Reserva Rioja waiting for the right moment. :)
