Sorry I can't be more helpful, as I have no good answer. I do have good periods and bad periods.

Though not massively overweight (26.5 BMI), better eating and fitness habits seemed to have helped. Still working on getting to a healthier shape. Depending on the type of apnea, this can help a good deal.

Less electronics/screens in the evening. No more streaming tv/video games until right before bed. Jury's still out on the effects of blue light etc but I really try to limit my electronics to a Kindle (Oasis with the warm color temp feature) before bed.

I admit I didn't try too hard with different masks/setups, that could help. Though I was mostly using one of the most comfortable "nasal pillow" interfaces already.

I will second another commenter's suggestion of a more elevated pillow setup. I use a regular pillow with a buckwheat hull pillow on top. Bad for my neck but I've slept that way for awhile and have adjusted, it's hard to go back to a "more optimal pillow height".
