My CPAP machine is driving me insane: does anyone actually get used to this thing?

I have been struggling with obstructive sleep apnea for six months now, and honestly, the CPAP machine is proving to be a bigger challenge than the exhaustion itself. Every night feels like I'm trying to sleep while wearing a scuba mask that wants to blast air directly into my sinuses. I have tried three different masks, added a humidifier, and even adjusted the pressure settings, but I still wake up at 3:00 AM with the straps leaving deep indentations on my face. Is there a secret to getting comfortable with this gear, or am I just destined to be a lifelong mouth-breathing cave dweller? I am dying to hear if any of you found a 'holy grail' setup or if you eventually just accepted the bizarre reality of sleeping with a mini-jet engine strapped to your head. Does the annoyance ever actually fade into the background, or do I just need to recalibrate my expectations for what a good night's rest feels like?
