I also have a few other things going on with my sleep and I don't think any of my local doctors are knowledgable enough (or willing) to get to the root of my problems.
You can read about some of it here:

At this point I'm considering going to one of the National Sleep Centers and would like to hear any experiences (good or bad) that you'd like to share.
Below is some data I've compiled from SleepyHead at my prescribed pressure. I've had 4 sleep studies done at three different local sleep centers over the past 12 years and each of them have determined that 12 cm is 'my' number.

I'm pretty sure I don't have a number and APAP and Bi-PAP have actually proven worse in regards to lowering my AHI so I feel it's time to start over.
