The short answer Most people need two to four weeks before CPAP stops feeling like a device and starts feeling like part of going to bed. The first few nights are usually the hardest. Almost every problem people quit over — a leaky mask, a dry mouth, air that feels like too much — has a fix, and none of them require you to tough it out alone. Week 1: strange is normal The first night you may sleep three hours. That is not failure. Your face is learning a new sensation and your brain is deciding whether to trust it. A few things that help right away: Wear the mask while you are awake. Twenty minutes on the couch with the machine running, watching TV, teaches your nervous system that nothing bad happens. Turn on ramp. Ramp starts the pressure low and builds slowly, so you fall asleep before full pressure arrives. Put it back on. If you wake at 2am and rip it off, put it back on. Partial nights still count and still build the habit. Week 2: the mask conversation By the second week, the machine is rarely the problem. The mask is. Leaks that spray air into your eye, red marks across the bridge of your nose, a strap you keep tightening — those are fit problems, not willpower problems. Tightening a leaking mask usually makes it leak more, because the cushion needs to inflate against your skin to seal. Loosen it slightly, reseat the mask with the air running, and see what happens. If it still leaks, you probably need a different size or a different style — a nasal pillow instead of a full face, or the other way around if you breathe through your mouth. Mask sizing is not one-and-done. Call us and we will walk through what you are feeling and what the fix usually is. Week 3: dry mouth, stuffy nose, and humidity Waking up with a mouth like sandpaper is the second most common reason people stop. Two causes: your humidifier setting is too low, or you are mouth-breathing and the air is escaping past your lips all night. Turn the humidity up a step at a time. If you get condensation in the tube (called rainout), a heated tube or a lower bedroom temperature usually solves it. If humidity alone does not fix the dryness, a chin strap or a full face mask keeps the air where it belongs. A stuffy nose can be the opposite problem — too little humidity, or seasonal allergies stacking on top of therapy. Mention it to your clinician before you decide the machine is causing it. Week 4: reading your own data By now your machine has been quietly recording. The number most people are told to watch is AHI — how many breathing events per hour you still have. Under 5 is generally the target, but your clinician sets what is right for you. Also look at usage hours and leak rate in your machine app. If your AHI looks good but you still feel exhausted, that is worth a call. Feeling better is the point; the numbers are just how we get there. What to tell your clinician Be specific. "I hate it" is hard to act on. These are actionable: "Air is blowing into my left eye about an hour after I fall asleep." "I wake up at 3am every night feeling like I cannot exhale against the pressure." "My mouth is completely dry even at humidity level 5." Each of those has a standard fix — a resize, an EPR/pressure-relief adjustment, a mask style change. Keeping supplies on schedule Cushions flatten, headgear stretches, and filters clog. Most insurance plans allow replacement on a set schedule, and worn parts are a leading cause of leaks people blame on themselves. We track your eligibility and reach out when items are due, so you are not doing math on a calendar. Your next step today If you are in week one, wear the mask for twenty minutes while you are awake tonight. If you are past week two and still fighting a leak, contact us and we will start with mask fit before anything else. 1150
