The only thing that worked for me was taking panadol to reduce the head cold pressure, getting a box of tissues, a bottle of water and going to bed.
I also had a fair amount of chicken soup - good for keeping the fluids up too.

I have heard that cleaning out your sinuses eg with the saline nasal spray can help you re-coup orate earlier because it cleans the bacteria out.

I hope you get better soon, and that you don't get another cold
