I have had some allergy symptoms, too. Not bad, take-you-out ones, but part of me thinks that some symptoms are the price I pay for living in a wooded part of the country with lots of green.
Cayenne helps -- anything to get stuff moving up and out.
One thing that makes me think that some reaction to all of this pollen that coats every inch of available surface outside is just how it is: my two-year-old daughters have some sneeziness, too. I think it is pollen. (It could be the abundance of cat and dog hair in which we all live, but it seems to be recent -- no real congestion, but they have pretty perfect little systems and are still a little sneezy, so some of it must be just the body's reaction to the invaders...?)
