do you have an impending feeling of doom?
Increased heart rate?
Increased anxiety?

If yes, I'd suggest that you ARE having a reaction to the medication and would recommend ceasing it and talking to your GP tomorrow about alternatives. I have seen this happen with anti emetics in the past (moreso maxalon).

Stemazine (more commonly known as Stemetil) is the best medication for vertigo or a combinationg of dizziness and nausea. You could try other anti emetics but they won't be as effective.
