lost my voice, Iodine?

I worked at a charity with a leak in the roof and a huge mountain of used clothes that got leaked on to.

At the end of every shift, I lost my voice. When I woke up, I could speak again, but not like before.

Today, I just did not go to work. They need to fix the leak and get their stuff together, and their unwillingness to do so is insulting to all of their employees.

I used to get a sore throat along w/ the voice-loss, but now that I take a bunch of Iodine, the soreness is gone, except when I do not take Iodine regularly.

My voice is taking a while to recover, and it does not sound like normal, not at all.

The Iodine takes the soreness away, but is it helping or interfering with my voice-recovery?

Could that soreness be a part of some sort of my body's own internal healing process? Could the Iodine be interfering with something? I'm mercury toxic, and that may be effecting it. I'm going to take another Iodine dose (bladder-wrack) and hope it's not interfering and hope I get my voice back in a week or so.
