My eyes, mouth and nose gets really dry. I need to get a humidifier myself.

Yes......mine does. Usually overnight. When I shower or wash myface it
seems to really help (and to be honest..snorting a bit of water also as I
don't like nose drop stuff ) Also, the past couple of months - my throat
and mouth really get dry and I drink/swish with water but I could drink
forever... that helps....but then I have to pee every 2 mins. Gum and sugar
free candies help also. My mom thinks it's all from the heaters, etc.

I don't get sores but mine is dry and I always feel like I have fuzzes in my nose

I also have Sjogrens and so have dry eyes, mouth, throat, nose and very dry skin. I use PUR Mints | Aspartame Free | Made with Xylitol | Sugar Free, Vegan, Gluten Free & Keto Friendly for dry mouth when i can’t drink enough or just too dry air. And at night i use Oracoat XyliMelts Dry Mouth Relief Moisturizing Stick-On Melts (works great) otherwise even with humidifier i still wake-up every hour or two with throat so dry i can’t swollow. These were recommended when i went to a PBC conference.

This is a symptom of a flareup Crohn's. May also be a symptom of PBC. I use a saline nasal spray & saline gel to keep my nostrils moist. I have both conditions.
