A couple of new questions

This is my data for the night before last.

I woke up about 11:00. The chart shows that from about the time I woke up until about the time I went to sleep, that the pressure was zero. I hadn't taken my mask off and nothing seemed unusual, so does this make any sense to anyone?

I'm scheduled to see my doc on March 16th.

So I've had the machine since about the middle of September. This is my 6 month checkup. If it wasn't for the fact that the machine seems to have controlled my snoring, I'd throw the thing out the window. In six months, I've probably had a dozen nights of 7+ hours of uninterrupted sleep. I've had one night where the AHI was under 1.00. Ironically, that was my best night since I've gotten the machine. Typically, I run somewhere under 2.00, usually around 1.50, but the AHI doesn't appear to correspond to having a good night sleep at all.

Around mid-December, my GP, Psych doc, and the Sleep doc's asst. all suggested Klonopin (since I had already been taking that for anxiety for 5 years, or more, maybe once a month (0.25 mg).

Whenever I make a change, it might work for a night, or two of better not great sleep. Example. Changed the lower pressure, because of hypopnea, from 6 to 7 about two weeks ago. Worked for maybe a day, and after that, things were back to the same. Nothing else was changed.

I would so love to drop this machine, and the doc, from the top floor of the Willis Building (old Sears Tower).

Typically sleeping about 1-1/2 hours before I wake up. Up for 45-hour and back to sleep for another 1-1/2 to 2 hours.

Feel as if there's just been no progress.

Statistically it looks like a good night. Low leaks, few events. I don't see the zero pressure you're talking about. It looks like you stay at 7.5 all the way to 2:00 AM when you have a pressure increase to around 10 as the machine responds to some snore and FL. The RERA indicates you may have been aroused by the pressure change.

This looks successful, but maybe I should feed the beast (Den) a bit and suggest you might be sensitive to the pressure changes. A constant pressure might work for you. If you want to try it, I'd suggest setting Min pressure at 9.0 and Max pressure at 9.0 and see what happens to your feeling of being rested. This would stop the hunting and pecking the machine does to find optimum pressure (those spikes of 1.5 pressure changes), and I don't see anything that would be a problem at that pressure. Conventional wisdom says CPAP pressure should be set around your 90% level, but I see nothing above 8.5-9.0 that is meaningful.

Oops. Sorry. Didn't look at the scale close enough. Just saw the flat line for an extended period of time, which I've never seen before.

Nope. About 4-5 hours of total sleep. Asleep for maybe an hour and a half and then awake for an hour to an hour and a half.

Thanks for the comments.

I'll try that tonight. I sure as heck have got nothing to lose at this point.
