I've seen many mention having had a sleep study. I have a terrible time getting to sleep and staying asleep and i never sleep more than 2-3 hrs at a time and i am a very light sleeper. pain in the left half of my body (my left arm feeling like a piece of dead wood and my leg feeling similar but not as bad as the arm), pain in my neck and anxiety add to the trouble. i have a memory foam mattress topper and a memory foam pillow and they used to help but now they dont. I was thinking of asking my fibro doc for a sleep study. Are they expensive? Can someone tell me how a sleep study works? I figure I'd be too self-conscious to "sleep" in front of someone knowing i am being watched. LOL!
