1) If what you call Optimal is the pressure you were titrated to in your sleep study, you should eventually start to level out and experience better quality sleep. It's not uncommon to have some mask issues, and pressure issues in the beginning. Most of these pass with time and patience. But the personality type of the patient ends up being 90% of the determining factor for success.
2)At higher than optimal pressures, many things can occur. Such as, headaches, pain in the throat or sinuses, pain in the chest and lungs, aerophagia, bleeding ears, bleeding nose, and the irritation that comes from difficulty in exhaling comfortably.
3) At lower than optimal pressures you may experience daytime sleepiness, wake up feeling unrefreshed, snoring, untreated apnea.
It's not uncommon to need an adjustment made to pressure within a couple weeks of initially beginning xpap treatment. Just because you were titrated to 10cm, does not mean that 11cm or 9cm might not be better.
