An opinion writer for The Guardian describes his experience with sleep apnea and trying to use a CPAP mask.

I was sent home with a device to which my chest and finger were tethered for two consecutive nights. The data thus harvested was sent back to the clinic and I awaited the firm diagnosis, that I was by now hoping for. I take medication for hypertension, reflux and couple of mental health issues and the sleep man had said apnea was probably at the root of all of these.

I have been using my CPAP for two weeks now. I fall asleep quite overwhelmed with serenity. Then at some point, two or three hours later, I awake in a panic, tear the mask off and go back to a troubled sleep. And that’s all I have to report at this stage.
