You could try using a mask/cushion liner. They sell ones that are disposable but they are pretty pricey. There are also reusable ones you can purchase or you can try and make your own. This might be more comfortable and reduce your sweating.
No experience, but I know it's very hard for me to use my CPAP when I'm having issues with toothaches or sinus trouble. The pressure just adds to the pain. Are you taking anything for it? I was sore for quite a bit after my wisdom teeth were out so it could take a couple weeks or so.
Unfortunately, I don't have any good advice for you as we have our own separate bedrooms now. Although I'm the one with CPAP and I don't snore, I'm a very light sleeper and we don't have the same sleep schedule. I couldn't handle being woken up when he came to bed or during the night when he gets up to use the bathroom, sets his alarm an hour early and hits snooze. I have to say I kinda love having my own room, so if you don't find a way to make it work it's not necessarily a bad thing.
I get a little bit of congestion at night sometimes as well, but usually it's worse without the machine. I try to blow my nose and clear everything out before I put my mask on and usually do okay this way. But when I went to a fixed pressure (which was lower than the auto was going to) I had to get up during the night and blow my nose again because it wasn't enough to keep things clear. We put it back on auto with a lower range and it seems to work better.
Is your treatment being monitored by a physician? Because it doesn't sound like it's working for you if those are your numbers typically. Treatment is considered successful if your AHI is under 5. I would talk to a doctor and you may need your pressures adjusted. I'm not sure why they would range so much one night to the next other than things like the position you sleep in can be a factor. How much REM sleep you get one night vs. the next? But regardless your treatment isn't working if those are your numbers.
I was told I would have to adjust the temp based on the room temp and/or humidity level. That said, I never got it to work well so I had to turn the heated part off and just use it like a regular hose. I had too much rain out so I went back to using the regular hose. Did you possibly move the position of the machine? I also have to keep mine on the floor as it helps.
I've had defective parts before so anything is possible. If nothing else works call your medical supply company and check with them.
A separate 2 night study is standard where I go. That's how mine was done. Only after they diagnosed the sleep apnea through the first test did they order an overnight study with a CPAP.
I don't know about feeling suffocated, but I think it's normal to require higher pressures when sleeping on your back. So if you have an autoset machine it might be just going up to a pressure level that is making you uncomfortable. I have found it very hard to tolerate on my back myself for that reason and pretty much stick to sleeping on my side.
I just wanted to share this here as I have continued to struggle with a lot of fatigue even after successful treatment of my sleep apnea with a CPAP machine and I know a lot of people here have as well. I've done all the diet and exercise stuff over the years without any noticeable difference. I also went on anxiety/depression meds last fall thinking maybe that was effecting things more than I thought it was. Still not feeling great. I took Nuvigil for a few days but didn't notice it doing anything outside of causing me some high blood pressure and slight nausea so I stopped.
One of my children had been recently diagnosed with ADHD and I noticed a lot of similarities in myself, with the one exception that I'm rarely ever hyper and usually the exact opposite. I decided last week to do some googling on ADHD and fatigue and found that many adults with ADHD have difficulty with daytime sleepiness and difficulty waking in the morning as well as sleep disordered breathing. The more I read about other issues with focus and inattention the more I was convinced this is definitely something I'm dealing with, and my psychiatrist agreed that I have all the hallmark symptoms of Inattentive ADHD. He's starting me on a low dose of a typical ADHD stimulant drug so we'll find out if it's going to help or not. Of course one of the side effects is insomnia and talking to other adults who have it, they often have to take meds to help them sleep at night with or without the stimulants so I may end up needing that in the end as well.
I know there are a million different things that can cause excessive fatigue, but this isn't one that I ever would have considered or suspected. Just thought I'd share this here in case it helps anyone else. It's still too early to tell if or what course of treatment will be effective for me, but I really do feel like I just found a huge piece of the puzzle.
Feeling hopeful for once.
I have to stop reading other people's experiences online because I think they give me too much hope sometimes. I went into the CPAP thing thinking it was going to change my life and while I did improve in some areas it wasn't quite the life changer I hoped for. Decided to treat my anxiety and depression with an SSRI in the fall too and with the combo of CPAP and those I'm at a tolerable level. Don't feel great, but I can get by with a few extra naps without feeling awful. So the doctor prescribed Nuvigil to try and give me a little extra energy during the day and she told me I could take it as needed so it didn't need to be an every day medication. Mind you it's only my second day, but I don't feel anything except some nausea at the 4 hour mark. I'm reading from other people how it was so strong they couldn't even stay on it or how they felt amazing on day 1 and I'm starting to worry this is not going to work for me either. I'm usually really sensitive to meds so if anything I expected to have too many side effects and feel wired, but I went back to bed this morning and did a little around the house but have still felt most of the day like I could crawl into bed and go to sleep again.
Has anyone here tried Nuvigil and had it take time to work, like build up in your system? My impression was that's now how this one works. Or have it just not work for you and try something else?
