I need some advice! Suffering at night!

Hello all! I have the worst time sleeping at night. It's pretty gross, so TW.

I have nasal polyps. I actually have AERD.

I wake up covered in snot and my mouth is dry from sleeping with it open. This does not matter if I take allergy pills or if I take Nyquil before bed. (Desperate and, strangely, I'm not affected by the acetaminophen it contains. (I'd die if I took a Tylenol.)

Anyway, I have to blow my nose CONSTANTLY, even when my polyps are not super flared up.

This is disrupting my sleep schedule and killing my self-esteem.

Does anyone suffer with this? Would an air purifier help? ANY advice is appreciated, thank you.
