Hmm, thanks, I'd never heard of that. We'll see if that helps next time.
She had brain cancer years ago (it's in remission) and she has double vision now and doesn't really have any balance. Usually what happens is, it'll be really hot in there, and then suddenly she can't see anything. She's still conscious (I guess) but basically it's like I'm helping a really drunk person out - and I'm sure that's what everyone assumes. As soon as she gets some air, she's fine. So I don't know if she's really passing out or not - I've never passed out.
