Yes, but likely unnecessary. Though unless you're drinking alone you're probably having some salty nuts or other snacks while you drink so really water will be fine. These solutions are for people who are in serious acute dehydration, which you won't be after a night of drinking unless there are other factors.

Simply drinking a large glass of water before going out, and having a glass of water after each alcoholic drink, is a pretty good way to avoid a hangover.

(also the water will help you pee out a lot of toxic crud that your kidneys have kindly removed from your bloodstream for you).
