Oh, carp, Lambchop! Vertigo is the worst.
Save yourself some money and buy meclazine in larger bottles that cost less. It's the same thing as the brand Antivert and it helps me a lot. When you talk to the doc, ask how much you can safely take in a day.
When the vertigo is really hard on you, you may start vomiting and need to take it again. It's brutal, I sure hope you can learn to control it for yourself.
Please be extremely careful driving!
