Not the OP, and I don't use a CPAP, but just living with sleep apnea is kind of horrible, and not harmless. It might be genuinely worth the small risks associated with the affected machines if the alternative is having to go back to untreated apnea.
It's annoying that they're so restricted here with all the medical red tape. They can't even go high enough to do actual damage. It's not like a respirator.
Or do they take foreign prescriptions too?
