My arsenal: Zyrtec, Claritin, Benadryl, Sudafed (sometimes all at once), plus raw local honey, local beer, Neti pot, and Tree Mix from People's Pharmacy.

If all else fails, Plan B: there's nothing to do but take a vacation from Texas. It's for health, right?
In the meantime, I invented another emoticon: :*(
