hi ya erin,
i think vertigo is one of the worst symptoms of ms myself. deciding what to do about a flare up is right up there too. if it were me i think i would ask him to call in an rx and then you can pick it up ''IF" things don't simmer down for you.
none of us like the side effects it causes however on the flipside we don't care for sitting on the fence and waiting it out either

if you have the rx called in and there for back up at least you have that choice if you get my drift. nothing worse then imo then not having your neuro at your fingertips and heaven forbid it be a weekend or the middle of the night. with that said i hope you can manage without them
