What do you find helps preventing dizzy spells?

Hi my name is Maddie and I am new to this I was told I have vestibular migraines a week ago after being diagnosed wrong and treated wrong for three years. I know by now my tr4iggers but I wanna know what you all find best to avoid them. I was told I need a fresh food only diet and a few other things I wanna know if you guys have tried the dieting? Does it work not work? at this point I will try and do anything to prevent a dizzy spell my vertigo is so bad.

I find the best thing for the dizziness is clonazepam

You said that you already know your triggers. What are they? If you know your triggers then there may not be a reason to go on the migraine diet.
