You woke at 3am and the mask was on the floor again. You don’t remember taking it off.

About a third of people prescribed CPAP stop using it — a number that hasn’t moved in twenty years. That isn’t weakness. It’s that nobody taught them the things in this book.

The 30-Night CPAP Reset is a troubleshooting system, not a list of tips. One chapter per reason masks come off — leak, air, panic, dryness, rainout, congestion, noise — each with something to try tonight and a way to check, in your own data, whether it worked. Then a 30-night plan front-loaded on the first week, where the research says the outcome is decided.

What you get, instantly:

• The book — 148 pages, designed PDF (reads well on tablet and phone) and EPUB for Kindle/Apple Books
• The 30-Night Log (2 pages)
• The Doctor Visit Prep Sheet
• The Mask Selection Flowchart
• The Data Cheat Sheet — the five OSCAR/SleepHQ shapes and the pattern-to-action table
• The Try-Tonight Checklist — the whole book on one page
• Free updated editions when prices, models or regulations change

Every claim is referenced — 207 sources, from peer-reviewed trials to manufacturer manuals and FDA notices, checked September 2026. No supplements, no cleaners, no course.

Not medical advice. This is an educational guide to living with prescribed CPAP. It never tells you what pressure to use and does not replace your sleep physician.
