Flea, go get
Mucinex and some numbing throat spray. Do the HOT water and salt thing as well before the spray. Take TWO mucinex up front and drink plenty of water, as this stuff will dry you up.
Mucinex will clear up the snot, which makes you lose your voice and makes ya cough. They have two dif ones, one with expectorant, and one with expectorant/decongestant. The latter raises BP, just in case you needed to know that.
Rest until you have to go, and it also wouldn't hurt to try one of those new sudafed things, they have one that is a plug in and one you can toss in the shower while you cleanse.
Keep with the chicken soup, no caffeine or alcohol (nyquil if you are desperate) and don't get dehydrated. Continue Echinacaea and vitamins. C and Zinc are important atm. They make cough drops with those in them and they taste great, Ricola IIRC.
Last resort, whiskey, lemon juice & honey... one shot and my throat was always cleared up. Gramma used to give me that until I finally had to have my tonsils removed.
If I think of anything else I will be back.
