Here's my list of rides to avoid, if I want to keep my vertigo under control. I have diagnosed vertigo, but have always struggled with motion sickness. I take Bonine every day when at WDW (25mg meclizine) to be able to "do" what I can, but here is what I try to avoid:
MK: Space Mountain, AstroOrbiter, Tea Cups, Barnstormer. I can usually handle one trip on Dumbo, Magic Carpets, BTMRR, Liberty Belle, Carousel. I don't like Splash Mountain, but that's because of the drop. I have done it 6 times, and it's the drop, not the vertigo, that makes me avoid it.
EPCOT: Mission Space (either side). I am OK on TestTrak BUT the outside part, where you go around the track at high speed, is touch and go, I ride because it's so much fun! I don't do well on the Friendships inside World Showcase Lagoon, but am OK (if I've taken my bonine) riding them around the Boardwald/DHS waterway.
DHS: No Tower of Terror, Rockin roller coaster, Star Tours, Toy Story Midway Mania. TSMM is worse for me than ToT!
AK: No Primeval Whirl (Hurl! as DD calls it), Everest. I have to be careful on the Safari but LOVE it, and can only do one round of Dinosaur or Kali River Rapids.
Parking lot trams, monorail, and buses would do me in if not for the Bonine.
