Mine only stopped doing it after I had flown a LOT. XD; Like... a lot. Like my dad had a plane. I stopped getting airsick, too. But until it stopped on its own, I had still not figured out what to do about it. (I mean, if yawning and blowing and all that stuff didn't work, obviously, which it doesn't always..) Sorry. D:
Hmm, maybe if you held your head ear-down over a steaming pot of water, or, I dunno, squirted lemon juice in there or something. I never tried stuff like that. Of course it might make things worse, but sometimes you have to make sacrifices in the name of... science? XD;;;
