When starting out on CPAP, the response will vary from person to person.
Some people will notice benefit, sometimes significant benefit, from night one. Others can report feeling sluggish and lacking energy.
What is usually found is that benefits will eventually appear in people once they allow some time to become accustomed to it. It can take up to 9 months to notice full benefits from using CPAP, so persistence at the start is important.
There are a few trains of thought with CPAP therapy. In some people there is an initial period where “sleep debt” is paid off. That is, after all of that time where poor sleep has been the norm, the patient has a new found good quality sleep, and sleeps a little longer each night to pay off this sleep debt. However, it must be remembered that the body is built to adapt. Over time, your body may have adjusted itself to deal with poor quality sleep. It may take this same amount of time to adjust to sleeping “normally” again.
CPAP takes time and persistence. Commit to using it for a period of time to see if there are benefits gained. If there are, get as comfortable as you can with it, then continue using it. If you are finding you are not getting benefits from using your CPAP device, it is a good idea to chat again with your Doctor or Healthcare professional.
