I've been without a voice the whole week due to having the flu. I think I've never sounded this ridiculous. Or well, I didn't really sound like anything at all.
Honey water for a sore throat is a classic. I heard that the combination of honey and cinnamon makes a good antibacterial-cokctail and and blended those with other flu-classics like heaps of fresh ginger and lemon and, of course, hot water. I've had several liters of this (and so does Dag, in a more diluted version).
It was also pretty nice to let half a glass of this soak over night and then filling the glass up with orange juice from the fridge in the morning.
