need a sleep study, what can I expect re: privacy/binding/etc

[the-infector.livejournal.com]

I need to schedule a sleep study but don't know what to expect in regards to what sort of environment I'll be sleeping in, how much privacy I'll have, whether I can avoid having anybody see me without my binder (I don't mean sleep in it, but like, being covered up/not having to move around once it's off).
