A gargle with warm salt water always helps when I get a sore throat. Just make it about as salty as sea water, maybe a little more. Don't overdo it, though, or it'll get irritated again.
Shot of Crown, honey & lemon warm it up a little. Halls drops make it worse for me but if you can get some Luden throat drops or Ricola ones. Rock candy also helps me.
Yea, I have been drinking a ton of water...more than usual. I left home with a froggy voice but it has since gotten so much worse and with the sore throat to boot. And disney, with 2 little kids in tow is not some place I can rest my voice either
