When you notice your mouth is dry, picture a lemon being sliced so that you can see its juiciness and pulp. Another tip is to take the tip of your tongue and let it lick the roof of your mouth 3 to 5 times and then swallow the saliva which has collected on the middle of your tongue. The third suggestion is to wear slacks or pants with large pockets and carry a half-pint of spring water. These small bottles can be purchased in plastic bottles with a collection of 4-6 for a reasonable price. Sip throughout the day.
