I got a CPAP for obstructive sleep apnea and it resulted in absolutely zero benefits after several months. It did cost quite a bit and take time to clean, though. I'm very skeptical about the positive effects of CPAP for all but the most severely affected individuals.
One trick you can try which I found really helps is, if you can, to shave before bed. I get a much better seal with a full face mask this way. Over time, you may find the cleaning gets easier. It is crazy how much you have to learn on your own about this condition. You should not have to get advice from random people on the internet; the field of sleep medicine w/r/t OSA treatment is still woefully underdeveloped. Once you get the machine, if your AHI looks good, there is not much more the sleep doc will do for you. The "treatment is working" even though your sleep may continue to suffer, e.g., you continue to wake up throughout the night. A CPAP cannot not measure the time awake after your sleep is interrupted, while you wait to fall asleep again. As far as the CPAP diagnostics indicate, the treatment is working.
If you stick with it, you should see some benefits, such that if you cease using it for a night, you will notice the effect. Good luck.
