Feel more tired

Day 3, I feel exhausted. Thought it would be the best sleep of my life?

Are you waking up a lot during the night?
I woke a ton with leaks, needing to move the hose, just feeling strange & uncomfortable & just hyper aware of the machine. Lots of wake ups will make you not feel rested.

PKS - a little info would help - like what spec. model of which machine, what mask, pressure settings, etc. etc.

It may take a few nights for your brain to adjust to that foreign thing sitting on your face while you sleep.

It can take many months before you feel better. Using CPAP is a huge adjustment.

Some more information from you could help you get more targeted input. We don't know if your treatment is therapeutic, how much you are sleeping, how fractured your sleep is, if your mask fits well or if you fight it all night, or if you may have other health contributors to how you feel. When I felt worse after starting treatment there were multiple factors that needed addressed before I could feel well rested. My machine settings needed changed. The pressure was too low and I was overusing the ramp feature. Some tweaks after coming here turned my treatment around. I still had horrid sleep due to a limb movement disorder, chronic pain, and medication side effects. It is commonly reported to feel worse before feeling better. Got some thoughts about that.

One is that once our brain/body figures out it can relax and sleep safely it leans into that heavily. When I first was able to get some real sleep I craved it - couldn't get enough of it. For the first few weeks of therapeutic CPAP treatment, I allowed myself to sleep more than is generally needed for routine functioning. There's a period of recovery time after sometimes years of the onslaught of untreated apnea. Any time we are healing we are advised to get plenty of rest. This is a healing process. Another thought that makes a lot of sense to me that someone else posted here was that with untreated OSA our body is flooded with stress hormones. Treatment relieves those stress hormone levels which have kept us on alert and there can be a resultant feeling of "letdown". Surely that will vary greatly fom person to person, but it could be a factor.

For actionable steps, I suggest you...
* Determine through machine data that your treatment is indeed doing what it is supposed to do.
* Address any equipment/mask issues.
* Look for possible contributing issues to how you feel. Other medical conditions? Med side effects? Deficiencies in things like Vit D or B12?
In the meantime, know that feeling better even when none of the above are at issue can take time and come so gradually as to be nearly imperceptible. And know that how you start is NOT an indicator of how well this treatment is going to work for you. Three nights is barely a blip on the radar of your treatment. Be kind to yourself, pursue nurtritional soundness to give your body what it needs to heal. And expect to see results from your perseverance.

It took me 18 nights, I think, to feel ANY better! It takes awhile for the body to adjust I am told, and that is very true in my case.

HANG IN THERE--it DOES get better! There may have to be some trial and error with masks and sleeping positions and pressure settings.
