Flonase nasal spray! It helps stifle the production of it so it won't sit on your throat and irritate it. I've been prescribed it for 15 years for the same problem (not allergy related), but its OTC now 😊

Also you could mix some salt in warm water and gargle it for a few minutes or a little Apple cider vinegar with warm water

Honey will soothe it

I had the same but found nothing to help 😑
