Keep hydrated. Keep hydrated. Keep hydrated. Keep hydrated. It can never be said too much. Sometimes, you may need to drink a litre per hour or even more. By the time you feel thirsty, you are well and truly DEhydrated. Keep that fluid going in. It doesn't really matter what sort of fluid it is (water, coffee, beer, milk, etc, etc) as long as more fluid is going in than is being lost.
