Hello, @robjohn - I"m sorry to hear that you have lost your sense of smell. I can imagine that would be frustrating.

I'd like you to meet @hopeful33250 @johnbishop @arlenephoto @stephenmcelroy @ramblyn. Hoping they may have some thoughts on your Parkinson's tremor and loss of smell, plus your concern about the ammonia fertilizer impacting this.

When your neurologist diagnosed you with a Parkinson's tremor but not full-blown Parkinson's, was the potential connection between the Parkinson's and loss of smell, and any tie-in with hauling loads of anhydrous ammonia fertilizer (NH3) as a truck driver, addressed? If so, what did the doctor say about these?
