Eat some local honey, even here in NYC a lot of people do that, they buy some a farmer's markets, but it has to be locally harvested, don't know if that's an option for you but it helps.
I may be speaking too soon, but so far I've just had one bad day of what I would call allergy symptoms, usualyl in the morning I want to scratch my eyes out, accompanied by sneezing all day, so far just one day of moderate sneezing . . .knock on wood.
