Our drink problem

To give some indication of what the weather is like out here, a typical day goes like this...

After drinking at least a pint of fluid before setting off, we each knock back about 8-10 pints of water, milk or whatever we can get our hands on during the 7-8 hours we are on the road. On the drive back to our hotel we usually manage a 3 pint carton of milk between us, followed by a pint each of whatever disgusting fizzy drink is available during the evening meal.
