Hello. I understand how unsettling these sleep changes and nervousness can be. Yes, some of your medications, particularly Amicon (amitriptyline) and Ethilam Pro-40 (etizolam and propranolol), affect your brain's sleep cycles and can sometimes trigger sleepwalking, sleep-talking, or increased anxiety. While these symptoms are not immediately dangerous, they do require attention for your safety. Please do not stop or change your medications suddenly, as this can make symptoms worse. I highly recommend discussing this with your doctor soon so they can safely adjust your doses or find gentler alternatives.
