CPAP is a machine that forces air through a tube into a mask fitted to your face, continuous positive air pressure, I think. This is prescribed to people that have sleep apnea. I was diagnosed years ago with this disorder but could never get use to the mask and would remove it in the middle of the night. I disregarded the diagnosis but continued for years to have trouble sleeping, tired all the time, always taking naps etc. After 6 hospitalizations in six months for pneumonia, heart stint and atrial fib, the docs told me many of these problems may be a result of not treating my sleep apnea. There has been a new mask designed that is much easier to wear and started wearing in December and EVERYTHING changed. Wonderful sleep, no tiredness, no more naps and no balance issues, ever. This was absolutely incredible because I had extreme balance problems. I use to have to walk with a cane many days, haven't picked one up since. I wanted to share this with others that might have sleep disorders and how that can have a tremendous impact on balance and quality of life.
