You can eat or drink whatever you wish, provided that you have DIET soda. Double Bacon Cheeseburger, Diet Soda.
I see this one all the time in bars. Whiskey Old Fashioned. You take a sugar cube, pour about 2 shots of whiskey and some bitters on it and top it off with soda. Then you garnish it, usually with olives, mushrooms or Brussell sprouts. Between the sugar, alcohol, carbonation and sodium the people would be better off drinking strychnine and juggling rattlesnakes.
Ah, but if you have them with DIET SODA, well, that makes all the difference in the world.
