The meds are very drying. I suffer from this anyway and medicine is adding insult to injury. There are saliva substitutes in various brands. The one I use after trying everything to keep from choking at night is Biotene. I use the Biotene Gel at night. I use about a 1/2 an inch of the gel and rub it all over top and bottom teeth with my tongue. Then I swallow a similar amount to moisturize my throat. It works for me. If I have to get up, I repeat. I've got severe Sjogrens and by doing this, I've been cavity free, dental problem free for three years. There are other brands available, I'm just giving you my opinion. Burning is a problem for me and other brands may be fine for you.
