Hi again! Yes it is from the MG my body works overtime to get the air I need when I am sleeping. They saw this at the sleep study I had and it wasn't too bad to sleep there. I did ok despite the cords etc they hook you up to. I live in Canada so that's how we do it here. The U.S. does do things a bit more progressive in some areas of medicine then we do. Hope you find your answers. MG is a journey of learning.
