Apnea sufferer here, for whom cpap stopped working after weight loss. It turned out that my mouth was opening during sleep, reducing the effectiveness of cpap, and after adding a chin strap to keep my mouth shut I have had very few apnea events. The mouth-tapers aren’t always wrong (though we do always look silly).
