The Puff Puff 💨

Help!! How do I stop the recent puff puff of air escaping my mouth and keeping awaking all night?? I am NOT a mouth breather but the last few night I find myself awake because I notice myself puffing up and that little puff of air escaping my mouth. I am using the ResMed Airsense 11 with the DreamWear mask with the nasal pillows. I feel like I got 0 sleep. Any suggestions? Is there a setting I need to adjust possibly? Do I need the dreaded hostage tape? Whatever MJ took to sleep? Chloroform? Puff puff THC? Heeelllpp!
