Slurpees, my new least favorite thing next to soda

I hate carbonation, my brother is a liar, he told be slurpees have no carbonation. So i get mine take a sip and my throught starts burning (as it usually does when i drink carbonation, thus my reason for hating soda) And i take a few more because the carbonation isn't that bad. But then it turns out the idoits didn't put enough syrup in the mix so their's airpockets everywhere. I hate slurpees, soda is equally bad. this sucks so much.
