Hi @mattie77 - You are not alone. I had some trouble also and think everyone does when they first start using a CPAP. My sleep medicine doc suggested I wear it while watching TV for 20 or 30 minutes to get used to it and that did help a little. One of the things that I struggled with was the pressure settings on my CPAP. It was originally setup with 8 to 12 for the operating pressure and I would fall asleep for awhile and the pressure was too much for me and it would wake me up. I found out that the ramp up feature starts it at 4 and it works up to around 8 which is supposed to be the optimum for my sleep apnea. Now when it wakes me up I reach over and tap it to set it back to the ramp up pressure and I can fall back asleep. I don't have to do that often now but was doing it regularly the first few months.

I had a follow up appointment with the sleep medicine therapist a month or so after I was diagnosed with sleep apnea and she was my best source of tips for using the CPAP. Finding a mask that you are comfortable with and feels good is probably the hardest thing for most people starting out. I went through 3 different full face masks the first 2 months after I started using a CPAP. Then the sleep medicine therapist told me about cloth covers for the mask that make it feel better on your face so I ordered some and have been using them ever since. It might be something to try if you think the mask is a problem - https://cpapcomfortcover.com/

Years ago I tried a full face mask but did not succeed in falling asleep so I gave up on the CPAP. Then a couple of years ago I tried again. After a week of not sleeping the salesman gave me a nasal pillow mask to try. Much more pleasant. I got used to it after a few weeks. Maybe try one. Mine is a Resmed p30i. Good luck!
