Cleo, arsenic poisoning would have flu-like symptoms, but, unless you are cutting the wood, I would think it would be somewhat unlikely if that deck had been out in the weather for many years. You can confirm it in a few months when your fingernails and toenails grow out a little more. I would suspect seasonal allergies or some airborne irritant more than arsenic.
For me, just another day of writing code, following up on a ton of work that was supposedly done, and trying to get things more in order so I can begin the hiring process yet again.
