I think it boils down to if you're thirsty, then drink.  Sometimes I may
feel only a slight thirst but I may feel vaguely lethargic or slightly
headache-y, and drinking some water makes me feel better.
I read a study where if you're used to drinking a moderate amount of coffee
daily (2-4 cups) your body compensates after awhile and it's not as much a
diuretic as most people think.  However, alcohol is a diuretic and is very
dehydrating.  Rule of thumb is to drink a glass of water for every glass of
alcohol that you imbibe.
