I am 71 now and if there is a sudden change in the weather from dry to damp I still get a blocked nose and sneezing and I was only in the job for just over 12 months.

that is interesting, that is my experience too.. But I've not read that anywhere as a symptom of zinc fever.
I had one bad case of zinc poisoning and it only affected me for a couple days.
A few years later i had one bad case of chlorine gas poisoning (i was attemtping to make a downs cell for producing sodium and calcium from their chloride salts), but it was only enough chlorine that i smelled chlorine for a day or two. nothing to actually damage my lungs.
Between those experiences and the lead exposure from going through several pounds of solder over the years and some exposure to mercury but probably not enough to notice..
I think i've lost at least half of my sense of taste and smell, and i'm only 26.
