@sheritaylor Welcome to Mayo Clinic Connect! The members will see your question in the morning, but, in the meantime I just wanted to welcome you and tell you that you’ve really come to the right place!
Is Sjögren’s syndrome a new diagnosis for you? I’m sure everyone here can help you with it. I, too, have very thick mucous in my mouth, especially at night. I find that OTC allergy pills really help. You might ask your doctor about them and see what they recommend.
