do you drink a sports drink as well as water? on the aids lifecycle ride i alternated water and a dilute sports beverage. folks who only drank one or the other suffered from dehydration and or electrolyte imbalances. i don't know what the symptoms are of either but that "nothing left in the tank" feeling sounds like what i had on day 3 even though i took on gallons of water.
