Hi Jock,
Currently here in Jerez. Spending average of about 50 euros a week including: beer, petrol (50p a litre), taxi fares (divided by 4), the odd pizza/McDonalds plus the usual bathroom stuff. So a pocket money budget : about 3000 euros for the duration.
Have spent a few bob on getting home to see the missus but even that's not been too bad. Have managed to get home every time with Iberia/BA for about 250 euros.
