Aw hun, colds are the worst dragging out awful things. Hope it doesnt last too long.
A couple of things for you to try.........cut one of your fresh onions up and put in a clean jar, cover with brown sugar and leave overnight. Take a spoonful of the syrup as you need it for a sore throat or cough. Have a drink of hot lemonade before bed, it makes you sweat so you may not sleep too well, but it helps shift the bugs.
Sore lips and nosies.....just plain vaselene or if you're completely organic ... almond oil?
Get well soon ;)
