Hi Carol,
I have sleep apnea, actually diagnosed with severe case of it and had to go to a BI pap machine. I did some research and from what my sleep apnea doc has said, it can be related to heart issues, but it can also be related to having been hit in head and can be a brain issue. If it's not severe, usually it can be controlled by losing weight. I go in for my surgery on Tuesday, this is a repeat, and I hope it makes a difference. I also plan to continue to keep weight down to see if that makes a difference. I can tell a difference if I don't use the bi pap machine, but I'm praying this will maybe at least get me to go back to just a regular cpap machine.
Godspeed and I'll see you on the other side.
