I’m really glad to see this side discussion on dust mite allergy happening here. I’ve had dust mite allergy since childhood, and I even had adenoid removal surgery at age ~7 to address it. Nothing seems to help.

I think dust mite allergy imitates some of the symptoms of sleep apnea, because your nasal passage gets blocked at night, waking you in a similar way to choking.

I’ve reached my mid-30s, largely ignoring the symptoms, but over the past few months I’ve been experiencing a truly terrible bout of insomnia.

I think it’s time to take the allergy seriously again. I’ll follow your guide and make some changes. If I could suggest an improvement to your guide: it may be useful to have a section (perhaps chapter 5?) on symptom relief. I’ve had friends say that a neti pot works wonders, for example.

Either way thanks for posting!
