Allergies. How do you combat this seasonal enemy?

When I moved away from Tulsa, OK three months ago I thought that I was leaving behind a good deal of allergy problems. Tulsa has a lot of environmental factors (natural and man-made) that make it a difficult place to live for anyone who suffers from allergies. In Tulsa, it is not a question of do you take allergy medicine, but the question is what type of allergy medication do you take. Unfortunately, Portland, OR has not been to kind on my allergies either. At the moment I am blaming it on the fact that we haven't had a freeze and it is already December 11th.

I have tried most of the prescription medication, and all of the over the counter medication, with a small amount of success. My latest combination is Zyrtec, Mucinex D, and Advair, but I want to investigate more natural and homeopathic solutions. One approach that I am going to do is take a teaspoon of local honey every morning. In order to make honey, bees often use the allergens in the environment. The theory is that if you take a teaspoon of local honey every morning your body will get used to the allergens and not react to them.

Please post any ideas you have that might help with allergies.
