Take with a bottle of water - one of those ones with a thingy on the top to stop the water spilling everywhere. Bottle can be re-filled with other cold drinks once you've drunk the water, if required.
Tried to find out what the thingy is called. Suggestions from colleauges include nozzle, teat and nipple, but there doesn't seem to be a definitive answer. But I'm sure you know what I mean!
