Are you absolutely sure about that?
Like you, arezius is in France. He adjusts his own settings.
And he has not reported his doctor objecting and taking the machine away.
He said they only care about compliance (more than 4 hours per day.)
This is his message after a doc visit and why he decided to take control of his own therapy.
