Immersion therapy.
Get a job running an open air swather for some old farmer for a couple of weeks.
You will either be cured or die.
This is true. I grew up with bad seasonal allergies. About 10 years ago I started biking to work year round every day I wasn't on-call.
The second spring/summer I noticed I wasn't taking allergy medicine and wasn't having issues.
Daily exposure for two hours while exercising ended up with me not having allergies at all except during the worst of the pollen, and then it is completely taken care of by some Claratin
