Yes and no. Drinking a glass of water for every alcoholic beverage may help stave off dehydration and dilute your blood alcohol levels (BAC), which are inherently helpful to your liver.  Drinking water and eating food in between drinks can help your liver metabolize the alcohol more efficiently.  However, there comes a point in the evening when your water intake can be offset by too much alcohol. This strategy works if you drink moderately but not so much if you binge drink.
