How do people obtain regulated medical devices like CPAP without a prescription? I assume a sleep study is required to get a prescription from a doctor.
There's probably some safety concerns, but I've become cynical about a lot of it. Doctors of course want everyone to go to the doctor first, but is it really that dangerous to use a CPAP machine if you didn't need one?
Apparently dry nose and skin irritation. I wouldn't worry too much about it. But if you can get a doctor's appointment you might get an insurance to pay for your experiment.
It can be preferable to going through the "proper channels", since it can take many months to get the machine through the US medical system, and you need to get some goddamn SLEEP.
