I am 17, live in Arizona, and just so happen to be allergic to pretty much everything here. I have ALWAYS had horrible allergy symptoms, as if I'm always sick, and everyone thinks I have a cold all the time! Anyways, I have been taking Zyrtec for about a year and it didn't help much (still bad PND, scratchy voice, itchy eyes/nose/throat, etc.) So now I am getting allergy shots, but I'm wondering...
