Well my first night didn't go too good. I think is was because I took a nap in the afternoon before bed time, so it took forever to go to sleep.
I had to take the mask off at 12:30am because I was very conscious of it. It seemed like I was concentrating on breathing in and out, and when I was relaxed enough to not think about it, I would freak out and think, "Did I breath.", and would end up taking several deep breaths in and out until I calmed down again. That happened several times until I couldn't take it any longer.
Early this morning I woke up and put the mask back on for about an hour until it was time to get up.
My wife has had her machine for about 3 months. When she first got it, I told her that she looked like a Jedi Starfighter with the mask on.
So now, that I have mine, I have joined forces with her Starfighter Army. LOL
She told me that now we need to get some of those Light Sabers that have light and sound, so we can have fun at night with them while we are masked up. LOL
When my wife got her PR REMstar Pro, I learned all about it, thanks to this forum, so I know mine pretty good already also. At this time I am going to leave the setting where they are. But I do know how to change all the setting.
