Hello. I'm Dr. Phil, licensed and practicing internist. Excellent service is my goal.
Thanks for this question
You are very wise to suspect your medicine as one of your two medicines is absolutely the cause
The amitriptyline is the certain cause this. This is a common reaction of this drug
This drug has what is called "anti cholinergic" side effects. One of which is dry mouth
If you stop the drug it will go away
If you need something else at night to sleep try a low dose of a drug called trazodone. It works well with few side effects
