In a survival situation you should begin rationing your water immediately even if you have a good supply. You have no idea how long it will be until rescue or until you find civilization. The general guideline is to drink no water day one. Your bodies reservoir will replenish this. Days two through four drink 14fl oz and days five onward drink 2 - 8fl oz daily depending on climate and water availability. Moisten lips and tongue while drinking, before swallowing. To avoid vomiting, sip slowly.
