I understand how you feel. That is an issue I am also struggling with. I have had primary progressive Multiple Sclerosis for 27 years. It is the most aggressive form of the disease. It has only been in recent years they even had a medication for it. I have only used muscle relaxers sporadically and use cannabis as my primary medication, diet and yoga for my MS. As with Dysautonomia, doctors do not understand either condition. Since I cannot find a doctor to advise me on what to do, I am going to do my own research and be my own advocate/doctor. I have no choice in this matter. I cannot find a doctor that will see me for atleast a year. If I were you I would keep the appointment to ask any questions you have and base your decision on their answers. You are very fortunate to have a doctor that you can get in to see. In the end, you need to do what makes you comfortable.
