Terrible allergies?

It's probably seasonal and I hate it too. I use Zyrtec at night. It's drowsy but it lasts 24 hours so before bed is okay. There is also Benadryl which is very drowsy also take before bed. Maybe Flonase or Nasonex. Flonase smells like flowers and the smell stays in your nose for 5-10 minutes and it's very refreshing. I used to use it. Hm. Try some herbal over-the-counter medications. The back of your throat itching is definitely allergies.
