I take a newer drug than salagen, called Evoxac and my rheumy who is really good says it works much better than salagen with less side effects. i don't notice any but if I take too much I might have too much saliva. I like the evoxac because it makes my eyes and nasal passages and gi tract all less dry, though it works mostly on the mouth. I haven't had a sinus infection since I've been on it and that's been over a year. I think I went through a sweating period, at night, for a few days in the beginning, but adjusting when I took it and how much. I have liver disease and am allergic to tons of drugs and I can take it no problem without excess sweating. That's just my experience. I don't use any sprays or mouthwashs, one pill lasts me the whole day because of my liver, but most people take it two to three times a day. In the beginning you might have too much saliva or sweat, but it goes away as your body gets used to the drug and you figure out what dose you need.
Sores in the corners of the mouth are often vitamin deficiencies but all that went away for me with the evoxac, so who knows. It's worth a try. it got rid of the tartar on my teeth and staining due to proper amount of saliva. I didn't even notice the dry mouth, I just figured it was just the way it was, my eyes were the bad part and it even helped them some.
Also, I have had both submandibular glands removed due to sjogrens, so I should be pretty dry and I'm not. Sorry to sound like an ad. I hope you feel better soon and can get this dry mouth cleared up. Chewing sugarfree teeth whitening gum helps me too. I used to use Carmex in the corners and it helped some.
