A way to get your BMI to <25.

On it, am a few weeks into exercising fairly regularly and eating much better, and have already seen a little weight loss.

OK, great, cause here's another thought:

It may be that your susceptibility to desaturations is somewhat weight- (and not entirely SDB-) related; the SDB issue may improve or resolve (let's think REAL positive here) with weight reduction; and you should do that anyway to get out of a bunch of high-risk health categories.

I did an actigraph once and it didn't capture anything that I couldn't capture with my sleep log. If I had a long period when I was awake, I knew about it, and so did the actigraph. Any short periods awake, it couldn't capture. I imagine it's good for cases in which people are convinced they aren't sleeping, but they are, and if you can show them that, they can relax a bit about their "insomnia". But not sure it's of any use for average insomniac. Just my opinion.

After mentioning the fitbit earlier, I decided to pick one up. Last night it recorded one time that I "woke up." This happened at around 2a, and that was pretty close to when my wife rolled over and kneed me... I will have to continue to use it for a few nights to see what happens.

Oh yay!

It's snowing again!

What a BFS!

Do you have a preference for how often I post the data from the smart card?

Upload the download to a third party server at least every 4 days.

When you write 'sleep quality' are we talking about consistent bedtimes, wake times, and few/short periods of insomnia?

Right. To try to calculate Sleep Time vs. Wake Time.

Even with the machine I averaged about 7 hours per night.

7 hours of what? Machine time? Time in Bed? Or Sleep Time?

I notice the log doesn't have a place for indicating whether I felt rested upon getting up, or how I felt during the day.

DIfferent form. Don't need it right now.

Does it seem like my xpap problems are more due to insomnia or mechanics?

"Compliance."

In re: mechanics, Barry thinks that SDB has "mysterious features" that can only be resolved by "complex algorithms". I don't. And I didn't subscribe to that even before the "expiratory instability" debacle. You apply 50 hours of concentrated support to anybody and you'll achieve compliance.

About your reminder...are you referring to the amount of sleep per night, or does it mean you are holding open the possibility my OSA is mild?

I think one needs to look at the net result of their entire approach in order to arrive at a rational decision.

Instead of "exercising fairly regularly", exercise religiously.

Instead of "eating much better", eat well.

If you're not losing one pound per week, your plan needs to be reworked.

Can you explain what you mean by this? What is "concentrated support"?

As for "exercise religiously" seems like everyone has a different definition. What's yours?

Mine might not be the best one you'd want to use.

Go with American Heart Association. That should be the standard.

I wonder why not? Well, I'll try something I think is reasonable, and adjust depending on weight loss. Would still be interested to hear yours.

It's not reasonable for you at this time. I'm a *****.

Which simply means that anybody can do anything if they truly want to.

Great! I'm in! As soon as I get through my Physical Therapy, let's do a triathlon together!

-SWS, what type of things might "stabilizing sleep" include?

Well, pharmaceutical sleep aids are one solution---especially if there are no outstanding problems with sleep hygiene, circadian rhythm, SDB therapy, counterproductive stimulants in diet/medication, etc. As a side note strenuous physical activity/exercise seems to really help increase my "sleep drive" or "sleep pressure". When I was a kid I used to happily run down to the store for Boston Baked Beans. And now we occasionally get sales fliers from the greater Boston area, and I'll run to the mailbox and back to retrieve those. That's the closest I'll ever come to Boston Marathon style running...

Perhaps there is CompSAS underfoot

I agree---especially if the central component of CompSAS is episodic or variable. However, central instability induced from excessive wake/sleep/wake/sleep transitions might be another explanation. I can offer my own wake/sleep/wake/sleep central-breathing controller skew as an example:

Secret agent girl might experience that same wake-to-sleep transitional phenomenon:

she kept the pressure at 5 for about 2 hours during which I was unable to fall asleep.

So, is this saying that sleep instability caused by unknown factors may be in turn causing a tendency to experience central apneas?

It certainly does in SOME people. The wake/sleep/wake/sleep example of central instability I cited earlier occurred when my wife and our two dogs happened to be making more noise than usual.

...Race you to the mailbox! Winner gets Boston Baked Beans!

That said (y'know, I never said "that said" before I saw -SWS saying it. Now it's like I can't stop.), I'm...

That said... there might be enough of us to get a That-Said Phrase User's Group going. Cool!
