Sorry I haven’t had chance to respond to your original post more comprehensively but did want to mention the doctors response part.

He expressed just a slight amount of doubt based on a previous inhaled insulins poor results (exubera) but then wrote the script. I was his first patient on it, he has since prescribed it to many more and seems to think highly of it…
It’s an approved medication for diabetes, you have diabetes… if your doc isn’t familiar with it and you ask for it and they’re not willing to become familiar for your benefit—- they’re not a good doctor.
