I am experiencing acute onsets of hay-fever-like symptoms. Very extreme and debilitating–sneezing violently for hours at a time.

Since I have no health insurance, I am treating them with Benadryl and regular bouts of outdoor exercise.

If I take supplements to help with my immune system, will this help with allergies?

I have experimented with this, and determined that whatever sets off the sneezing fits is coming from outdoors, not indoors.
