Diet Dr Pepper, please?

I'm from Texas, where Dr Pepper is king. Sure, Coke and Pepsi are good for what they are, but I don't want a cola, I want a DP.

For some time now, I've preferred to drink diet DP, because (a) I don't need the extra calories and (b) it actually tastes good for a diet soda. On the rare occasion that a restaurant would have diet DP, I'd get that, and I'd get regular DP otherwise, because everyone carries it.

Now that I'm watching the blood sugar as well as the calories, I'm strictly diet soda and tea. The problem is, diet Coke and diet Pepsi are NOT good for what they are. Why are there so few places that have diet DP on the soda fountain? Almost every restaurant has either Coke products or Pepsi products, and every slot in that soda fountain is filled with a company product except for that one left for DP.

(The ones I have found nearby that do have diet DP, by the way, are Taco Bell, the combination KFC/Pizza Hut, Chicken Express, and Jason's Deli. Also, when I'm in the mood for mystery fish, the combination A&W/Long John Silvers has diet A&W root beer.)

Why in the world, here in the birthplace of DP, are there not any restaurants that sell only DP products? There's a lemon-lime fizzy drink, root beer, orange, strawberry, grape, lemonade, and even cola! The next time you want a Coke or diet Coke, try an RC Cola or Diet Rite instead. Get a Moon Pie too. A diet Moon Pie, if you can find it. Get one for me too.
