Acid cured motion sickness?

Hadn’t really thought about this properly until today, but about 2 weeks I dosed 100ug at a music festival which had some fairground rides and I went on one of the swing rides where you’re effectively being span round repetitively in the air for 30 seconds-1 minute. Usually whenever I go on any sort of ride like this/in general I’m feeling really sick/dizzy during the ride and for a while afterwards. But I forgot about this when I got on until my girlfriend reminded me before the ride was about to start so I was fully expecting to have my trip taking over temporarily by feeling extremely sick.

But during it I felt no dizziness at all, no sickness when I got off, could walk perfectly fine and felt nothing like i usually do after getting off a ride. My girlfriend on the other hand who hadn’t dosed and very rarely gets any sort of motion sickness from rides said that she felt pretty dizzy after it. Does anyone know why this could be?
