Shocker! Cat's Psychiatrist Dad's Beauty Tip is Actually Good!

My father spends basically every waking hour of his life on psych wards making rounds, so he's not exactly whom I turn to for product recommendations. But, alas! Like many hard-on-their-parents daughters, I've underestimated him. He introduced me to this Biotene mouthwash, which specifically (and brilliantly) treats dry mouth (fancy term: Xerostomia) caused by (amongst other things) certain medications, psychiatric or otherwise. It's also good for coffee-guzzling editors who stress out a lot (another cause of cottonmouth), smokers, or just anyone who can't force themselves to drink water constantly. Accordingly, it's super-breath-freshening, but mild-tasting and gentle. I bought it at the drugstore (by the pharmacy counter, natch), but you can get it on Amazon.com for a mere $6.
