<<>  I have had an extremely sore throat for two weeks now. >>

Tony, 
Heres the way that CS works for me to get rid of a sore throat as drinking it 
did not do the trick.  I bought a small spray bottle (fine mist, blue colored 
glass from Space Savers)... fill it with CS.  When I feel a sore throat 
coming on I just sit with that bottle in my hand and about every 20 - 30 
seconds for about 10 -12 mins  spray into my mouth, aiming for the back of my 
throat.  I also inhale (through the mouth) somewhat when I spray which can 
cause a cough or two but it really gets it into my throat.  This method has 
worked numerous times for me.  The CS is approx 7 -   10 ppm.
I keep that same spray bottle on my kitchen sink for those little 
emergencies, its easier than a dropper bottle.
