Oh my gosh, Holly, that must have been terrifying. Thank goodness you weren't driving.
I had issues with fluorescent lighting from the get go. I had to keep the lights in my office off and just use a desk lamp set a ways away from me. It never failed - anyone that walked into my office would flip on the lights.

I finally put tape over the switch! The CRT would play tricks with my eyes, too. But, I never got vertigo.
I'd call the opthomologist as soon as possible. I'd call the Neuro, too, just so it can be documented on your chart. Not sure what, if anything, the neuro could do, though. I'm glad your DH was available to bring you some meds. It might be a good idea to keep some in your desk from now on...that way you're ready if it hits again.
I'm sorry for the scare you had....sometimes that wipes you out more than the actual symptoms do. I hope you get to feeling better soon.
