anxiety and meds give you dry mouth , my way round it I chew a cocktail stick it helps produce saliva . where chewing gum is cool to but give jaw ache , always try to keep your mouth from going dry it will give bad breath if dry, People say to me why you always got that stick in your mouth, I SAY WHY NOT
You have had anxiety for three years with a fine voice until recently. How do you know it's from anxiety?
I have had anxiety for many many years with a fine voice until a med I was on for 6 days gave me facial and neck tremors and really screwed up my voice. The Voice Dr. Says I have dystharia from the med and need speech therapy.
This may not be your situation, but our voices have the same problem. Mine may be worse.
I would highly reccomend you go to a Voice/Speech Dr. You will no doubtly get a script to start Speech Therapy before it gets worse. If your like me it won't get better by itself.
