Beginning this month, Pepsi has decided to revamp Diet Pepsi by adding a second artificial sweetener. According to PepsiCo, the company is adding a "very small amount" to the beverage, with the exact amount varying based on the the region where it's purchased. There's no telling what effect—if any—this will have on Pepsi's sales, but it's an interesting move. 

Sometimes, you have to roll the dice.
