I've been using the Dreamwear Full Face for a few months now (yes I've followed the replacement schedule and yes my profile is inaccurate.)
However, whenever I received a new full face piece, I noticed myself waking up less and less refreshed. I concluded it to be mask fitting issues so I readjusted my fitting, however this changed nothing.
I also began to have all day headaches, and I've had minor headaches waking up before, but these just wouldn't go away. Tension headaches on the sides of my head, and they're beginning to drive me mad.
I started to notice how the vents in the Dreamwear would constantly find themselves obstructed either by my hair or by my blanket.
Recently however, I noticed that I have large dips in my total leaks, and I cannot find any explanation for them.
The pressure sometimes will go up while the total leaks remain constant. The mask at my pressure is expected to have around a 25 or so leak rate, however there are extended periods of time where it will drop to 18 to 15 for around 5 to 30 minutes.
My blood CO2 levels last measured in July were 34 mmol/l, these dips have appeared occasionally throughout my usage of this mask. Some nights there are absolutely no leak dips and others they are completely everywhere.
Can't find any further information on the forum, mainly because whenever I search for leaks I just get excessive leaks rather than leaks under the expected amount.
