Well, they gave me a sleeping test kit first, But something went wrong, so I got the watch thing with the sensor for two nights. Turned out I have sleep apnea. My partner did not hear me gasp for air at night either, but I felt sleepy during the daytime so they got worried I might have it. Turns out I do, and since August I have been Sleeping with a face mask on. It sure does the job, but I agree, I hope when I lose the weight I will no longer have two use it.
