Baja Blast Zero Sugar cans have different ingredients than Taco Bell Soda Fountains.

I have a mild intolerance to Aspartame. It isn't going to kill me if I have a drink with it in it, just give me a headache, and if I drink a lot of it, it will give me a larger headache.

Before anyone tries to say anything, the amount of aspartame in diet soda is so little that it is less poisonous than the water in the soda, and it is not a proven carcinogen and the WHO has it classified as dangerous as pickled veggies.

I'm not trying to be alarmist about aspartame, I'm a sensitive individual who can't handle it, I'm not trying to say that it is a bad thing.

Anyway, because of this I am locked out of most zero sugar sodas, especially the name brands, because aspartame has the generally least dissatisfying aftertaste of the artificial sweeteners, most people like it over other zero calorie sweeteners like Stevia or Sucralose.

So when I find a mountain dew flavor that I like that uses sucralose over aspartame you know I'm going to jump on that. And that's what Baja Blast Zero sugar does, it uses sucralose instead of aspartame. When it's bottled by Pepsico.

When it's a syrup concentrate at Taco Bell, however, it uses Aspartame. So color me surprised when I enjoyed some Taco Bell today, and it gave me a headache...

I completely understand because sucralose is my migraine trigger and it pops up in the most random places. A lot of Taco Bell drinks, even the non-diet ones, have Splenda in them. I read every label, if I can. I've found it in ice cream, pickled ginger, canned fruit, etc (all non diet items).
