Oasis is a great way to keep your mouth from drying out in situations where you can't get something to drink. It has a pleasant mild mint flavor, and just 2-4 sprays can keep your mouth moist for 2 hrs or more. Great for pre/post op, guard duty, those with fluid restrictions and more. Available at Wal-Mart, Kroger, and most chain drug stores, and comes with a coupon inside for $1 off on next purchase. It is located in the mouthwash aisle, and also comes in a mouthwash form.
