Hi there Sleepless in Galway - My son also experienced sleepless nites because of dry mouth and tried all sorts of things but for him what really worked was "Stoppers 4Dry Mouth" - available over the counter at drugstores like Walgreens. The first time he tried it he was able to sleep through the night. He also uses a warm air humidifier. Sometimes you have to try different things before finding what works for you.
