I went to a convention in LA last month and when I landed I had the worst vertigo. I had never experienced it so I didn't know what was happening. I could barely stand up but that really didn't stop me because it was the convention I was looking forward to for months, there were people I hadn't seen in forever or ever in real life (just talked to online) so basically I just took some Excedrin since that's what I had and fought through it. Luckily it was almost gone by the first day of the con.
