Oh, Lou… Wish I could recommend something to make you better. Only thing I’ve found to help with any condition in mouth or throat is rinsing/gargling with warm salt water. I know it is a “treatment” usually meted out by annoying aunties but, well, I’ve found it works, even if only a bit. Mrs T assures me that Waitrose do the best yogurts that can be got in supermarkets. Take a peek at the website, plenty of choice. Take it easy, hope tomorrow is better.
