Funny I stumbled into this forum, I just had one last night to check the settings on my CPap.

All the electrodes, the small bed and not being able to sleep on my stomach did not make for a restful night sleep. From what he told me I should start using a chin strap to keep my mouth closed, they will need to change the settings on my CPap and the amount of times I woke from pain in my back and legs. The leg & back pain I knew about I just had a spinal fusion 3 months ago and with the weather change the past couple of days I've been miserable.

I've been waking up tired and from the night time oxygen monitor tests they could tell my oxygen levels dropped below 88% 4 X so it warranted me to go for the sleep study. So all in all it was pretty decent news.

Other than possibly not having a good nights sleep while you are there you have nothing to lose and only something to gain if they can find something to give you a better nights sleep.
