Ugh, I completely know how you're feeling! I used to be like that too. Don't get disappointed. It's not easy to get used to a CPAP machine. Years ago, I bought a CPAP machine without a humidifier, which was a complete waste of money. There is no benefit to using that type of CPAP. Now I use an automatic CPAP, and it has a very nice feature that automatically adjusts the pressure during the night. It is my second CPAP, and it helps my nose stays clear, stops my snoring, my mouth doesn't get dry from mouth breathing all night, and helps me wake up in a very energetic mood.
