Luffy, like you I started out with a sore/dry
throat, I have upped my intake of water a bit and also suck tic tacs, although you might prefer something different, the sucking on a sweet seems to be the best so far at easing the throat discomfort.
Truthfully it's alot less of a thing now than it was to begin with, and a whole heap load better than morning bird cage mouth from cigarettes.
