In a shaker, combine the vodka, orange juice, and juice of one lime. Add a few cubes of ice. Cover and shake well.

Fill two medium-sized glasses with ice. Evenly distribute the cocktail between the two, leaving a bit of room.

Top off each glass with the lime-flavored mineral water. You can do this to taste, using more or less dependent on your preference. We used about 3 or 4 ounces in each glass.

Stir gently to distribute. Top with a lime wedge and serve chilled.
