But when it comes to the somewhat popular carbonated beverage known as Red Bull, Lena Lupari isn't just a customer; she's an entire market unto herself.

Beat that, Garden State Ultras! THIS IS WHAT COMMITMENT LOOKS LIKE That's three thousand calories' worth of sweetened chemicals every day, along with an annual tab of $9,000.
