Ten years ago, I was running on fumes without even realizing it.
I survived on late nights, random sleep schedules, and too much caffeine.
I convinced myself this was normal.
It wasn't.
Here’s how fixing my sleep completely rewired my life. ↓

Sleep doctors often treat insomnia and sleep‑disordered breathing as separate silos, but in real life they overlap a lot. If you’ve been treated for one, did anyone on your care team seriously assess the other?

Many “racing mind” awakenings are actually micro‑arousals from effortful breathing that never show up as full apneas. Have you ever noticed your thoughts explode awake for no clear reason in the middle of the night? 😴

Home sleep tests can miss milder breathing problems that still fragment sleep. If you’ve got stubborn insomnia, would you push for an in‑lab study to actually see your arousals and breathing, not just oxygen dips? 💤

Insomnia + snoring, dry mouth, or waking with a pounding heart = a pattern that deserves a sleep‑breathing workup, not just another sleeping pill. What symptoms (even “weird” ones) show up on your worst nights? #sleep

“I can fall asleep, but I keep waking up” can be a red flag for subtle sleep‑disordered breathing, not just “light sleep.” If that’s you, have you ever had your breathing (not only your brainwaves) checked in a proper sleep study? #sleepstudy

CPAP comfort isn’t just the mask—it’s humidity, exhalation relief, leak control, and nasal health.
Which of these made the biggest difference to your sleep, and what are you still struggling with?

There’s more than one kind of PAP: CPAP, auto-PAP, bilevel, ASV. Many “failures” are really mismatches between patient and machine.

If CPAP feels like “too much air” or you’re fighting the machine, it might be a pressure / mode issue, not a you issue.

CPAP “failure” is common: research shows ~30–60% of users don’t meet basic adherence (≈4 hrs/night). If you struggled, what was hardest part?

Strange, vivid dreams in the mountains? Irregular breathing and frequent micro-awakenings at altitude shift you into lighter sleep, making dreams feel intense and memorable. Have you noticed your dream life change once you get above 8,000 ft?

High altitude already taxes your heart and lungs; dehydration thickens your blood and makes sleep even harder. Aim for clear or light-yellow urine and sip water steadily, not in big gulps at night. How do you manage hydration when you’re sleeping higher?

Your sleep can take 3–5 days to adapt at high altitude (CDC/NIH). Racing up by car or trail means more headaches, vivid dreams, and fragmented sleep. How do you pace your ascent so your nights don’t fall apart?

At ~8,000+ ft, thin air can cause “periodic breathing”, shallow breaths or pauses, then gasps that wake you up all night. Elevating your head 4–6 inches and keeping your tent well-ventilated can really help.

"Getting a good night's sleep will improve how you feel but also how long you live." – Dr. Andrew McHill, OHSU.
New study shows at least 7 hours of sleep nightly could be one of the most important health decisions you make.
