.....having a blocked nose

You wake up with a headache - still tired, struggle through the bowl of porridge and get into work. When you speak, your words are misunderstood more than normal.  The problem is obvious - a blocked nose.  What is the cure - tiger balm, Vicks vapour rub, anti-histamine, steam bath? There are many. They all work, or not, depending on something - it is one of those medical mysteries of the universe. Once back home, the inevitable question is asked - how was work today? The answer - it was okay, but I couldn't breathe properly - is met by the equally inevitable - yes, there's nothing worse than having a blocked nose.
