Too high pressure causing central apneas?

Does anyone have any information on this?
I was titrated at 8 two years ago and six months ago had nasal surgey done to repair a devatiated septum and the Pillar Procedure done (I have a long, low soft palate).
I continued to use CPAP but was feeling bad again upon awaking including dizziness and brain fog. My Dr thought the pressure was too low and set it at 10 without a sleep test. I am now feeling even worse so I stopped CPAP two days ago. I feel groggy in the AM but no severe symptoms. I saw in previous posts indications that too high a pressure can cause central apneas.
What are the symptoms? How does the pressure cause them?
I am not going to use the CPAP until I am retested.
Thanks....

Here is something I found on the subject of pressure-induced centrals. It comes from a post written by -SWS, perhaps the most highly-respected, knowledgable poster ever to grace the pages here at cpaptalk:

As it turns out, there are a variety of physiological factors that can cause central apneas. Some of those etiologies are completely unrelated, and so are their treatments. For instance, sleep onset central apneas can be purely anxiety-driven. In these patients the central apneas occur immediately prior to falling asleep. Then the central apneas disappear during sleep, but quite often resurface as soon as the patient starts to wake---including during intervening periods of wakefulness throughout the entire night. Some cases of central apneas are treated with CPAP and an oxygen bleed, most are treated with BiLevel, some with medication----and, of course, various combinations of treatments are often tried as well. AutoPAPs tend to strive to avoid pressure-inducing central apneas for those patients who are so inclined. Yet, AutoPAPs are probably not an excellent choice for taking care of central apneas related to neuromuscular dysfunction, or even those anxiety-induced sleep onset central apneas. Central apneas can entail an entire host of possible physiological failing mechanisms, requiring a host of treatment methods to treat the various etiologies.
