I am finally surfacing from three weeks battling The Worst Cold I've Ever Had. Seriously, it was nasty: I sincerely hope you don't catch it. However, should you succumb to this or some other respiratory virus, I highly recommend dosing yourself twice a day with a hot drink containing the following:
Juice of one lemon
1/4 tsp vitamin C powder (~1 gram)
a generous spoonful of honey
It may not cure you, but it will soothe a sore throat and help shake loose some of the mucus. My husband insists I add a splash of rum or cognac to his but I prefer the non-alcoholic version. Best results are obtained when consumed while wearing pajamas and watching Alone in the Wilderness or some other show about somewhere really, really cold.
