Unfortunately I've been down with the dreaded flu bug - though fortunately (or not) I didn't really lose much of my appetite! According to the doctor, you can take lots of things to relieve the nasty cough and sore throat, which I did, but felt most of them were a waste of money.
However ........... I found a good teaspoon of Manuka Honey in a hot orange or lemon drink (lemon or orange juice and hot water) is as good as anything, and seemed to work quite well. I sipped it during the night too, and this did help with the cough.
