What I've found to be the most effective for the dry mouth and thick secretions is bottled flavored ( Lemon ) soda water sold at Walmart as " Clear " for about 69 cents a 33.8 oz bottle. I swish it in the morning and the fizz cuts through the thick secretions leaving the mouth clear. Has no sugar!! I sip it from a cup all day long.... been a life saver for me. Give it a try and there are many flavors to choose from.
