The only mask I’ve been able to tolerate is one with nasal pillows. I have a lot of allergies that cause sinus congestion. I take Flonase, Zyrtec and Sudafed before bedtime. Despite the meds, I often become congested during the night. I then have terrifying nightmares of drowning or someone trying to suffocate me. I wake up gasping for air. Does anyone else struggle with this or have suggestions? I learned to sleep with my mouth shut so apparently my brain isn’t telling me to open my mouth when I can’t breathe through my nose.
