Those who can tolerate the general CPAP experience, have bed partners who tolerate it, and don’t experience detrimental effects should absolutely use it when there are no comparable solutions. However there are lots of perfectly legitimate reasons why not everyone can, and having alternatives (which do also come with side effects) to consider is amazing for the community overall. It’s legitimately great that it sounds like CPAP treatment has been effective for you (as it has for me, mostly), but your comments end up sounding quite dismissive of the challenges faced by other patients.
Careful skepticism of new treatments is always warranted, but even if it only helps 5% of patients with OSA in absolute terms that’s a huge population impact.
