any symptoms or problems you want to tell the doctor about (include symptoms such as poor sleep, trouble concentrating, feeling tired)
medications that you are taking (include herbs and vitamins)
upcoming tests or new information you've heard about
changes in your living situation, such as a job change
That way you won't forget anything during the appointment.
You may want to ask a friend or family member to go with you and take notes. It can be difficult for you to take notes and pay attention to what your doctor is saying at the same time.
