It would seem that ever since, every single morning I wake up with "the sniffles" and clogged sinuses requiring a steady stream of kleenex for at least a couple of hours. I don't get itchy eyes (he says as he rubs his eyes) or anything else really, just the sinus thing.
you probably developed alergic sinitus.
Change the air conditioner filters in your home and see if it makes a difference.
Take something like Tavest-D or Claryton-D (anti-histamine w/ nasal decongestant)
