Why does opening my throat and *gargling* with listerine, as opposed to merely rinsing like I would when brushing my teeth, hurt a lot? I don't have a sore throat or any other throat troubles I know of. [more inside]

I've had a stuffy nose, post-nasal drip, and consequent sore throat -- all due, I think to an allergy. It's taking several days to clear up, and clearing up very slowly. Should I be seeing a doctor about this? [more inside]

I used Crest Pro Health alcohol-free mouthwash about an hour and a half ago. Now I'm eating McDonald's and I cannot taste the salt on the fries -- in fact, I made my roommate eat some of them to make sure I was not crazy, as they tasted sweet to me, like they'd been honey-roasted. Furthermore, the cheese on my ketchup-free burger tastes weirdly like ketchup. What the heck did that mouthwash do to my taste buds, and is there anything I can do to undo it quickly? I put a pinch of salt directly on my tongue, and it tastes just like sugar!
