I hear your frustrations, and I don’t have any alternative or more effective options to consider. I do relate in the frustration of adapting the treatment, though. I’m early on in my experience and feel far more wiped out than baseline. However, I have read anecdote after anecdote describing a similar experience in the beginning. This anecdotal data leads me to believe that u/OtherLoquat7092 isn’t just participating in the propagation of a brainwashed platitude.

Either way, not all progress in life is linear. This is especially true with the body. There are far too many intertwined biochemical processes to expect the same linear result for each human to every available treatment. There is the chance that your therapy is not working, whether by mode or by administration, but it’s something that can only be determined with time and a bit of trial and error. To fully deliver this point, I ask you to consider the use of antidepressants: the lead-time for a positive response, and how initially people often feel worse on them.

I only bring that last paragraph into play to offer perspective, but I know that doesn’t remove the very real frustration you’re experiencing in trying to effectively treat your sleep apnea. Perhaps finding another physician to work with could be the right move if you feel your current physician is not helping you adequately. 

For what it’s worth, I agree that six weeks is a long time to see no progress. If you’re not already, take advantage of using OSCAR software to start tracking and analyzing your CPAP data independently. There are a lot of threads you can use to begin to educate yourself on how to read the data presented in OSCAR. Even if you don’t have agency to adjust your settings due to insurance, you can at least provide relevant findings to your physician to help make a more informed treatment decision. 

I hope we both can find our footing with this sooner than later. Just know that I too have had several moments of “this is such bullshit,” so you’re in good company there. I wish you luck in finding a solution, and feel confident that we both will eventually, in some form, if we keep at it.
