If you were recently prescribed a CPAP (continuous positive airway pressure) machine for obstructive sleep apnea and the first few nights felt awful rather than restorative, you are far from alone. National surveys and sleep-medicine literature consistently find that a meaningful share of new CPAP users struggle in the first weeks, and that early discomfort — not lack of willpower — is the single biggest reason people give up on therapy before it has a chance to work.
Why the first nights are the hardest
CPAP therapy asks your body to get used to something unusual very quickly: a mask sealed against your face, a steady stream of pressurized air, and unfamiliar noise, all while you’re trying to fall asleep. According to the American Academy of Sleep Medicine (AASM), it is common for new users to feel like the pressure is “too much,” to feel claustrophobic, or to wake up repeatedly while adjusting — and these sensations typically ease as the body acclimates, provided the mask and settings are actually a good fit.
The Sleep Foundation notes that mask type is one of the most common — and most fixable — sources of early CPAP failure. Nasal pillows, nasal masks, and full-face masks all interact differently with individual face shapes, sleep positions, and whether someone breathes through their mouth at night. A mask that leaks, presses on the bridge of the nose, or doesn’t suit a side-sleeping position can make an otherwise correctly-prescribed pressure setting feel intolerable.
What tends to help, according to sleep-medicine guidance
- Ramp and humidification settings. Most modern CPAP machines include a “ramp” feature that starts at a lower pressure and gradually increases it as you fall asleep, along with a heated humidifier to reduce dryness and irritation in the nose and throat. The Mayo Clinic notes these adjustments are often the first thing a sleep specialist or equipment provider will fine-tune.
- Mask refitting, not giving up on CPAP entirely. The Cleveland Clinic emphasizes that a poorly fitted mask is a treatable problem, not a sign that CPAP “doesn’t work” for you — most durable medical equipment (DME) suppliers will do mask exchanges within an initial trial window at no extra cost.
- Short, deliberate practice sessions while awake. Sleep clinics frequently recommend wearing the mask (with the machine running) for short stretches during the day or while reading/watching TV before bed, to let your brain associate it with something other than the stress of trying to fall asleep.
- Tracking data with your provider. Most CPAP machines log usage and residual events; sharing that data with your sleep physician or DME allows objective troubleshooting rather than guessing.
When to loop in your sleep specialist
Persistent leaks, mask marks or sores, ongoing insomnia after 2–4 weeks, or dread around bedtime are all reasons to contact your prescribing physician or equipment provider rather than quietly stopping therapy. Untreated obstructive sleep apnea carries real long-term cardiovascular and cognitive risks, so most sleep specialists would much rather troubleshoot an uncomfortable mask than have a patient abandon treatment altogether.

If you’re having trouble with CPAP therapy, talk to your sleep physician or equipment provider about adjusting your mask, pressure settings, or humidification rather than discontinuing treatment on your own.
