I don't know what it is!! Maybe it's the sweetener, but whenever I drink any Zero soda, or any Max soda, especially the colas. I get heartburn so bad that it feels like someone has been punching me in the chest for 3 days. And it lasts for about 3 days. I've tested the theory a few times at great personal risk lol. Anyone else experience this or something similar??? I think the sweetener is ACE-K. I can drink diet sodas and regular sodas just fine. I also had no issue with the Coke C2 or Pepsi Edge sodas.
