I was just over at Walgreen's, and in looking at their ad they now sell the Biotene there (the ad lists the Dry Mouth Moistureizer Gel, Toothpaste, and Mouthwash). In this week's ad, at least where I live, they're all on sale for 4.99 each.

Even at walmart, I seem to remember the mouthwash costing more than that (that's the only one I've bought)

I use it 'cause I have Sleep Apnea, and the air from my Cpap dries it out (plus I have had dry mouth for forver....long before finding out I had Sleep Apnea). I haven't used it a lot though, mainly 'cause of the cost....guess I better start to use it more, though!
