You're not a old dog. Your story is typical though.
Glad to hear that you are doing well.
Learning to live with your new best friend your bipap will take time. Don't be afraid to ask questions like how do I get my bipap through airline security when I travel.
Or how can I set up a back up power supply for emergencies.
It's all part of being a "hoser" , apneatic... or whatever you want to be. ..
I'm a crusty old truck driver who loves his cpap. .. I call him Charlie. ...
If you're talking about the hypoglossal stimulation. I'm pretty sure that it's still in research.
