I feel for you. My family and I get vicious migraines, not the sickness, but we see stuff in our peripheral vision (with the especially BAD migraines) roman numerals, flying fish...you get the idea.
So, do everything you can to ward those off, vicious, evil, nasty things they are.
I have heard of the aura migraines but I never knew some people actually experience what you describe. That’s pretty wild.
