decided on mask, undecided on machine

The S9 is Resmed and has a rear hose connection.
The top hose connection is on the PR System One machines.
There are many subtle differences between the brands, power requirements being only one.
If you get a good pure sine wave inverter the machines could not tell the difference between that and a standard US 120 V wall socket, except the inverter might provide more stable power.

Welcome leximorph19, a lot of us got the that feeling the day after the sleep study and you may get it the first few days after you start your treatment.
Normally it doesn't last but slowly over time it will come back.

Pretty much all parts are interchangable, personally I like sticking with the same brand for each.

Good luck

I got my machine at last and started therapy at home last night. At first, I thought it was bad timing because I was nursing a fever and had some nasal congestion + dry cough. But you know, I really felt better when I woke up. Fever was gone.

In a way, it was a little like waking up from the split sleep study - with less effects because I usually don't get enough sleep during week days. So, although I felt more awake while driving, at the office, I still felt moments of drowsiness. I hope my adjustment period doesn't take too long.

Thanks!
