I’ve been diagnosed (after a full night “Sleep Study”) with sleep apnea. While I had none of the obvious symptoms listed on their questionnaire before treatment, after they put me on the CPAP machine, I had most of the symptoms.
I tried it several times for a week at a time. They adjusted the programming & even gave me the “smart” CPAP machine.
I finally told them that “Who needs waterboarding? Just put the prisoner on this CPAP and he’ll talk after a week!”
(BTW, my problem is not the mask - I’ve flown using an oxygen mask with no problems at all.)
Your humidity was set too high.
