When one is distracted by music, Twitter, and the Chow hound's obsession with a little rubber ducky and one takes a large gulp of one's drink, forgetting that one has switched from Peach Tea to Diet Coke, one should remember the following tips in coping with the surprise:
1. Do not gasp in shock.
2. If one catches oneself mid-gasp and realizes one is about to fill one's lungs with Diet Coke, one should not clamp one's throat closed while still keeping one's lips closed.
3. One should remember in such a scenario that the only remaining viable opening prepared to absorb the momentum of one's mouthful of Diet Coke is one's nasal cavity.
4. When Diet Coke forcibly enters one's nasal cavity one should not reflexively snort.
Diet Coke, the new sinus douche.
