observations:
easy measurable gains I feel are a direct correlation:
1. concentration levels through the roof
2. annoyance levels reduced when working with people
3. mood is much better overall, I'm still a dick, but a better one I guess

Not so easy to connect directly to better sleep.
1. I don't feel the desire to game that much on my computer. -- Weird that... been a gamer all my life. Never really have that many OK... what do I do now moments.
2. I noted from initial cpap usage that light sensitivity went away, I love sunglasses and could not bear to step out without them. Now sunglasses are kind of optional. I can confirm that the same sensation of light sensitivity went down when resuming using cpap from a long break.
I don't think I will ever take a break from mr cpap again. I just wish supplies were a bit cheaper and the whole prescription thing is really weird for me. Almost feels kind of like a scam.
