Why is that, Coca Cola soft drink products always give me the hiccups, but not other carbonated beverages?
It makes me mad! And nobody likes the hiccups.
All that carbon is added to it. Some soda products have a higher percentage of carbon in it. Cocoa-Cola, Pepsi and are one of the largest companies with more added carbon. I do not drink soda myself too many times, so I know I can give you hiccups.
Diet Coke + Mentos
