Ongoing tiredness despite good AHI. Flow and Leak spikes despite mouth taping

Welcome! Both zoomed-in snippets show you holding your breathe briefly during an arousal. (The flow rate above the zero line is inhalation; below is exhalation; and at zero is a pause.) It's perfectly normal to have some brief arousals every hour during sleep. You may have been holding your breath while turning over in bed.

Your chart is a thing of beauty. Don't change your settings.

UARS is usually signaled by heavy flow limitations. Yours are very light.

It can take time to start sleeping well using a PAP machine. How long have you been at it?

I see that you were using the machine on the 17th for little more than 7 hours. Most people need at least 7 hours of SLEEP to feel rested during the day, and many need 8. You're getting less than 7, which is not enough. Try hard to arrange things so you leave 8 hours between going to bed and getting up, and try hard to go to bed and get up at the same time.

It can just take a while. You may still be reacting to the new experience with being conscious of the reaction. There's such a thing as sleep debt, which perhaps you are still paying off.

Do you have a copy of your sleep report? If so, perhaps you could post it (with your personal information blacked out).

You're on the right track with those blackout blinds -- the best thing you can do for yourself right now is to follow the guidelines for better sleep. They look kind of vanilla, I know, and you may also feel that you don't really need to follow all of them. But I would strongly recommend that you give them a try for a solid month.

• Keep a consistent sleep schedule. Get up at the same time every day, even on weekends or during vacations.
• Set a bedtime that is early enough for you to get at least 7 hours of sleep.
• Don’t go to bed unless you are sleepy.
• If you don’t fall asleep after 20 minutes, get out of bed.
• Establish a relaxing bedtime routine.
• Use your bed only for sleep and sex.
• Make your bedroom quiet and relaxing. Keep the room at a comfortable, cool temperature.
• Limit exposure to bright light in the evenings.
• Turn off electronic devices at least 30 minutes before bedtime.
• Don’t eat a large meal before bedtime. If you are hungry at night, eat a light, healthy snack.
• Exercise regularly and maintain a healthy diet.
• Avoid consuming caffeine in the late afternoon or evening.
• Avoid consuming alcohol before bedtime.
• Reduce your fluid intake before bedtime.

Also, be aware that what didn't bother you when you were 20 might bother you now. Our bodies change over time.
