Inflammation: You may be experiencing an allergic reaction to one of the ingredients or having a Vagal reaction to the cold temperature. In both instances, the mucosa of the aero digestive tract is exhibiting an inflammatory reaction, becomes swollen, congested and secrets mucus. Need to a void the slurpee.

Phlegm: May be allergic or a sign of silent acid reflux Avoid the slurpee
