Almost everyone starting CPAP is braced for the wrong thing. People arrive expecting the machine to be loud, and it isn't. They expect the pressure to feel like a hurricane, and mostly it doesn't. Then something nobody warned them about turns up instead — a dry mouth at 3 a.m., a red line across the bridge of the nose, the strange feeling of exhaling against something, water in the tube after a cold night, or the discovery that the mask is fine lying on your back and hopeless on your side. So: what actually surprised you in your first week? Post the thing you wish someone had told you before night one. New members read this thread more than any other, and the answer that helps them most is usually the small, unglamorous one. Two things worth saying out loud if you are in week one right now: The first fortnight is not representative. Adaptation is real, it is normal, and the numbers from those nights should not be read as a verdict on the therapy. "I gave up after three nights" is a very common story and not a shameful one. If that was you, come back and tell us what stopped you — often it is one fixable thing. Nothing on SomniTalk is medical advice. Talk to your own clinician before changing therapy.

Last thing, and the one that matters most in week one: the point of all this is not the numbers. It is whether you feel better in a month than you do now. If you are struggling — genuinely cannot tolerate it, or you are lying awake fighting the machine every night — that is a thing to raise early rather than endure quietly. Masks get changed, pressures get reviewed, humidification gets adjusted, and all of that is normal early-therapy housekeeping done by the people looking after you.
