I am a mouth breather, so I tried the full face mask. Exhaling and having hot air hit my face just makes me uneasy. Also, I never felt like I got enough air. I turned up the pressure a bit and it didn't seem to help. I took sleep aids and still ripped the mask off in my sleep.
I switched to nasal pillows. Those are far less intrusive, but after wearing them for 5-10 minutes, my nose starts to stop up, rendering the machine useless.
Thanks in advance!
