Yes I believe so. I had a cold just before Christmas, and my Mum heated a pan up of lemon, sugar, honey and water. It did ease it. Hot blackcurrent before bed is good, and to release bunged up noses I swear by airwaves chewing gum!
I'd advise that you take it really easy chick. A nice soak in a hot bath and plenty of rest.
Hope you feel better soon x x x
