Instal a "skinner box" while she sleeps

You didn't think of it before, assuming that the meds and the programing would be enough, but you need something more serious. Attaching a plain black collar with a property ident you activate it and start programing. Mostly the programing you already did on her will just be reinforced but you also add in triggers if she talks above a very low level and If she is outside of both the house and 300 ft of you.
