Smelling and tasting iodine?

I just noticed this yesterday... I was driving in a busy highway, in the wrong lane of course.. and my GPS was sending me all to the wrong exits. I was stressed and sweating and I kept catching the scent of iodine??
And today, my chest infection is back very slightly abd when I was coughing, I tasted iodine like 8 hours after I took it in my oj.

What does this mean? Nothing? Is my body sending it to my lungs because that's where it's needed?
