I think I may be suffering from xerostomia (dry mouth, difficulty swallowing, and other inconveniences due to lack of saliva). What should I do?

If you are suffering from xerostomia (dry mouth, difficulty swallowing, and other inconveniences due to a lack of saliva), you can try using a medication that contains Xylitol, which can help stimulate saliva production. These medications are available over the counter in the form of sprays or lozenges. Give it a try for 2 to 3 weeks and if it doesn't provide enough relief, consider consulting a dentist who can prescribe a more targeted treatment based on the cause of your condition.
