perhaps it means you are more immune to poison, so you don't need to vomit

I have a friend who absolutely loves getting the spins from excessive drinking. She liked to lie down and watch the room spinning.

I would need to ask her if she gets motion sickness.

I dont get any motion sickness at all, not on airplane, car, boat, etc.

If I drink enough to get the spins, I will /not/ get sick when my eyes are open, even when my eyes are clearly dealing with nystagmus.. but if I keep my eyes closed for more than 30 seconds, I definitely feel ill.
