I don't have apnea that I am aware of... I have trouble falling asleep and staying asleep, even with meds. What happens in a sleep study? What if by some chance I get there and sleep well? Any info on what to expect would be great.
Make sure they are checking to see if you have abnormal alpha waves and how often your deep sleep gets interrupted. I read a book , Figuring Out Fibromyalgia, written by a doctor, Ginevra Liptan, who goes through many of the medications and treatment options because she also has fibromyalgia. It was nice to get opinions from someone that not only believes in the disease but has it herself.
If you are being sent __something__ is going on with your sleep. Don't worry about wasting everyone's time. They will put wires on your scalp, electrodes on your chest, a tube under your nose, and wires on your arms and legs. Getting up to pee in the middle of the night will be a challenge!
The bed will be comfy, and if you can do what you usually do right before bed you should be able to fall asleep easily. They are looking for many different aspects of "not sleeping well" and should be able to at least make suggestions to do it better.
It's a lot easier than it seems.
So I am snore loudly. I told him my husband at the time was complaining. He thought it was good to look at possible sleep apnea. I did the test (which is pretty weird) and found to have pausing in my breath. The cpap allows me to sleep without stopping breathing (which wakes you up without you knowing). I wake up feeling more refreshed. I even nap with it now.
Be glad they are looking in your sleep pattern. They might find you don't get into that deep sleep level that we all need to feel good. I have a few members in my family on cpap machines which help them sleep. They go for routine sleep tests. Now there are home versions, where they hook you up at the office and you take the machine home.
