Hi nomad,   Dry mouth can be a symptom of having gone too low carb.  Make sure you are including at least one fist sized serving of starchy veggie every day, more if you are very active, feeling anxiety/depression, low energy or are getting poor sleep.  If you like you are free to post some examples of your meals in a day (include portions) and fluids, stress, exercise and anything else that might be relevant.  We can take a look and see if anything stands out.
