Maybe you could define better what you mean by "spacey". Do you mean that you felt ill and unable to focus or concentrate and that it was sort of emanating from your head? (I know, that's very vague and weird.)
Judging from what people say on this forum, there is huge variability in how people react to starting CPAP therapy.
I had an intolerance for the plastic smell of the first mask that I tried. It made me feel sick and dizzy just from breathing the odor. So I'm wondering if you were talking about something like a reaction to plastic.
Did you use an APAP during your sleep study? (Not clear if you meant a diagnosing study or a titrating study.) If you used CPAP or APAP in your study, I was going to ask you to compare that to your APAP use at home.
If I think back to my first couple of weeks of CPAP use (in February), I wouldn't have wanted to take a test or anything like that. In many ways, I felt better, but there was just a lot of stuff going on with my body - I remember that suddenly I felt cold all the time, and my balance was a little bit off.
It's actually a shock to your system when you first start using xPAP therapy. Your body is suddenly getting enough oxygen all night and you aren't having nearly as many awakenings as you were before, so your sleep stages start a gradual shift back to a normal architecture (theroretically).
Some people say they feel better than before while this is going on while others may find that it's a real adjustment period for them.
So I guess the next time you use your APAP machine, let us know how it goes. This forum has lots of experienced xPAP users.
Welcome to the Apnea Board forum, and good luck on your exam.
the spacey feeling is about the same as when I have taken a Percocet, very airy feeling with a slight bit more focusing required to concentrate on something.
WELCOME! to the forum.!
Hang in there for more responses to your post.
Much success to you.
