Regarding Xanax, no I did not have withdrawal symptoms. I took one pill.
Unfortunately, I did have the super-drowsy "hangover" effect the following day, which is common. I didn't like that at all.
But the main reason I'm avoiding the Xanax is that I don't want to develop a habit. I realize one pill won't cause a habit, nor will two. But I feel the whole thing is pointless if it's just going to provide temporary relief, just to be right back in my original situation after a few hours.
I'm also starting to question whether my LPR symptoms are fully reflux-related, or if they are due to a combination of factors. I notice, for example, when I talk more, the symptoms get worse. There is definitely some redness/irritation in my throat. I wish I knew a way to cure that. Rinsing with Biotene mouthwash does seem to mask the symptoms of the throat irritation, at least to some degree. Not sure why, as this isn't one of the stated uses of Biotene, nor has anyone on the internet reported the same experience.
