If I recall, the cold is a kind of virus with millions of strains - that's why it's impossible to cure. Sure you could cure a single strain, but that's not going to help you all that much. I mostly just grump about it and get on with my day, but mostly I don't suffer colds all that severely.
That said, I will milk it so that people will make me cups of tea and stuff, and sometimes, especially when it's at that stage where it makes your body feel like jelly, I end up cuddled up under my blanket and complaining loudly.
I also eat spicy food, because I hate it when my nose is blocked, and spicy food never fails to open it right back up.
