RE Vertigo
Have you guys tried the Releifband? My missus tried it in combination with kwells and she swears it works.
Its available from the US, no side effects.
As an addition to this i find your body builds a tolerance to vertigo the more flying, unusual attitudes, aeros you do.
It also makes a difference if your the one flying or a pax/student. As the pic your brain is busy and doesnt have brain space to waste on mixing visual cues with your senses.
