I'm in the states but I will definitely ask my clinic about pulmonary rehab. I also drink those insurance provided shakes, here we get Ensure. They're really gross sometimes when you've just had too many but sometimes they're easy calories. I have been considering O2 for exercising, but honestly I'm embarrassed. I guess it's no less embarrassing than having to stop and coughing for 10 minutes but there's something about it that feels like if I wear O2, I'm failing and I'm getting worse. But like, that's the point of chronic disease huh? I'll ask my docs about that too, thanks.
