Hi Sandy...and welcome again to the Forum.
You may need a higher start pressure to get comfortable with your therapy. Ask your tech to start you at pressure 5 at the very least. Most of us find that settings at 3 or 4 feel like room air to us. Your humidifier is set on its highest setting. Is there some reason for this? You may adjust your own humidifier setting and I would recommend a setting at 3 while you are adjusting to your CPAP therapy. You may also ajust your own ramp time settings. I reduced mine from 45 minutes to 10 minutes and this was a great help to me.
Even mild OSA can be very much helped on CPAP. Untreated, mild OSA can be very damaging to one's health over time.
It takes awhile to adapt to CPAP. There are a fortunate few who adjust right away, but most of us need a few months before we feel at home with this therapy. Keep up the good work. In time, you should feel much better. Good luck to you.
