When younger, we used to gargle with warm whisky and water........ it always felt better! I'm prone to bad throats. Honey, warm drinks, paracetamol and you'll usually be OK. A Big Thing is simply to stop talking, and it's awfully hard to do.
I am currently suffering exactly the same
I am adding a dash of lemon juice and large spoonful of honey
Apparently the honey coats the throat
The odd piece of dry toast or bag of crisps will also deslough the throat
