Will let you know how I perform tonight, thanks again...
If the air in your mouth problem starts turning into an air in your stomach problem, you may want to consider backing the pressure back down to your original range of 4-7 if your AHI < 5 at that range and you were not seeing significant clustering of events occurring when the pressure was at the max.
While it goes against conventional wisdom here at cpaptalk, there's nothing automatically "wrong" with allowing an APAP to hit its max pressure setting (frequently) if
your max setting is enough to control your apnea---as in your overall AHI < 5 and you are NOT seeing significant clusters of events when you are at maximum pressure. In other words, for a few people, very minor snoring and flow limitations can cause an auto machine to increase pressure to the point where it triggers aerophagia and/or spontaneous arousals caused by discomfort. And if you're one of these people (I am), increasing the max pressure beyond what you strictly need to control the apneas and hypopneas can lead to diminishing returns: The higher max pressure doesn't necessarily bring the AHI down any further, but it can increase restlessness and discomfort during the night, which then leads to less overall sleep and less high quality sleep, which leads to feeling lousy in the daytime.
