Here's a question for you one and all...

I am about to begin a 9 week run of performing 5 times a day every weekend in one of the most acoustically unfriendly environments known to man. That, however, is not really the problem. I can support my voice well enough, and rarely really have any issues.

Unless...

There has been a drought, and there is *so* much dust that you can get your RDA of minerals in one breath.

*This* irritates like no ones business, and I have had many moments where I came very close to losing my voice, as well as moments when I became ill (upper respiratory issues).

Any advice? (Beyond "wear a mask", that is)
