Anybody have it? Anybody ever had a sleep study?

I'm doing one in a few days and am wondering what it will be like trying to sleep with all that stuff stuck to me in a strange place (though they say it will be set up like a hotel room).

I've got several symptoms that could be explained away by sleep apnea (high blood pressure and depression being the biggest). I started cycling when I figured out my blood pressure was high in June but it would sure be great if that turned out to be sleep issue. Heck, I hope I do have sleep apnea just to finally feel better!
