Seemed like a fancy word at the time we officially 'met' but I was no stranger to the feeling. It all seems like a long time ago.
I don't remember the first time I experienced vertigo but it was probably in an elevator. The metal types that probably had poor sealing. It didn't matter if it was going up or down. I would feel this lightness in my stomach and head either way. I eventually learned to tolerate it - "no point going up any number or flight of stairs just because of a minor discomfort" i must have thought. I had a big fear of heights for the same reason too, even up to going out on balconies on floors that were far up above the ground (I don't think I have quite overcome this one).
I don't remember the last time I experienced it either - might be because the elevators in use these days might be better designed. I remember clearly though, the few weeks following my accepting to work for this company that required you to do a lot of fitness training as part of induction, I was worried about how far I would have to push myself. I was determined though....my mind was made up to not be a wuss. In one of those exertive-type trainings though, as I was at some 30ft height or so, going to make the drop in a spiral made of basket-like twine, I realized I could do anything I wanted to - vertigo or not.
