I don't think there is a medication going that potentially doesn't cause dry mouth.  It's the ones that give you hiccups or make you suck and blow like a fish that you have got to watch out for.  Then there are the ones that depress your blood pressure or simultaneously increase your appetite and reduce your metabolism.  Familiar to all who partake is the practice of taking medications to counteract the side effects of other meds.  And then there's addiction. Going cold turkey is generally not recommended, as this can lead to seizures, night sweats, shaking and irritability.  Irritability is itself a possible--if not probable--downside of benzos, which box you in better than a beehive. Especially watch out for the little green ones that pick your neurons out in neon, like Light Brite.
