Sorry you're dealing with this, Char.
Whenever I experience vertigo I have to be inside, not outside, as big open spaces make it worse for me. I try to lay down and keep the room as cool and dark as possible. Sort of like treating a migraine.
I had Antivert once and it helped but made me sleepy. Which I guess is a good thing because being up made me sick.
I cannot imagine having to drive with vertigo....please be careful if you do. I hope you're better soon. Don't push yourself too hard.
