Feeling Vertiginous

"Vertiginous" is one of my favourite words. I was very much looking forward to using it next weekend, when we will be celebrating Andy Orme's birthday at the top of the massive Blackpool rollercoaster. However, it is actually an extremely unpleasant sensation when your feet are on the ground and it won't stop. Ever since I arrived in Amsterdam, I've felt as though I were on a boat. I assumed that it were because I was. My middle ear is apparently unaware that I am no longer afloat, and is continuing to make me feel as if I'm sliding off the surface of the planet. I know, I know; some people pay good money to feel like this, in fact I have done so myself on many occasions, but now PLEASE MAKE IT STOP...
