I have an extremely dry mouth most of the day and as a result, an incredibly sore tongue. I also have a bitter taste. Is this a symptom of hypothyroidism or a side effect of Levothyroxine? Or not connected at all? I've had this for 5 months. Some days are dreadful. Some days are better. When I lie down the bitter taste goes but I wake in the night with a dry mouth. My saliva production seems ok - it doesn't make sense!
Any help or comments very much appreciated
