Oof, yeah... It's not a fun condition to have. I'm so sorry you got hit with this. I have no idea how any of the symptoms could possibly relate to snoring though. Oh yeah, maybe the fatigue..? Still. It's a relatively rare condition to have, and a lot of docs never figure it out.
I always had to drink with food. I couldn't get it down my throat any other way. Never knew it was a matter of not producing enough spit due to chronically inflamed salivaglands. The eyes require artificial tears, which isn't the heartache I thought it was going to be... The inflamed joints were another story. The doc wanted to put me on a small dose of prednisolone for that, but at the time I was still well over 100 kilo's and wasn't looking forward to gaining more. (And I didn't know I was prediabetic at that point either). You know how carbs are inflammatory? So's cow's milk, and eggs. I switched to goat's milk/cheese years ago, and after a while, when eggs became problematic too, I cut those out for a while. Once I started with LCHF the inflammation flare-ups reduced further, and sometimes I can have a little (cow) cream or butter! Not two days in a row though. But it was with keto that I finally got the eggs back into the equation, I think... Brain's a little foggy today, sorry. (Our cat passed away on Friday, so I'm not quite there.). The eggwhites used in the annual flu jab do turn my hip joint into ground glass for a few days, but that's the only time I still respond badly to something eggy. All in all, you figure out what works for you, much like with T2. I'm not on steroids for it, just the eyedrops. But I do remember a time where I had my hair cut really short because I couldn't hold a brush, and I couldn't turn/hold the key to the door without crying with the pain of it. Especially bad when it was cold. The pain would keep me awake at night, like a hot wire running through my fingers, wrist and hip especially. Cutting out the cow milk products reduced inflammation within a month. I got that tip for my mom's reumatologist over in Tilburg. (Mine's here in Baarn.) The weird thing is, when she first did the intake with me, she said "I know this sounds silly, but how much milk do you drink?" That was about a carton and a half per day, as I was rather big on milk. (It replaced lunch for me). She wrote it down and never mentioned it again. So when the other reumatologist suggested I quit the dairy for a while, that... You know. Lightbulb moment. I don't think I ever had neuropathy, but I can't be sure. My feet burned, got red and felt like a thousand needles were in them, but that's also a symptom of Hashimoto's. I haven't had a flare-up of that since low carbing and cutting cow milk either. So who knows?
All in all... Maybe looking at diet, again, might be beneficial. Because as far as I know there's very little that can be done about Sjögrens besides steroids and eyedrops, (Dunno if Amitriptyline would help for neuropathy that isn't caused by diabetes?) and with T2 in the mix... You might want to explore the alternatives first.
Good luck!!!
