This sweet and sour cocktail will put a shock to your system.
Place the Vodka, Blue Curacao, Sweet & Sour Mix and Lemon Juice in a cocktail shaker over ice. Shake that thing until it's chilled and completely combined.
Fill a high ball glass with ice, pour the contents of the shaker over it, and top it off with the lemon-lime soda. Garnish with a lemon wedge.
