i agree with all that it is YOUR decision...although I have heard that some MS centers push certain DMDs over others...
my neuro suggested Ampyra also. I had problems with it and told him I didn't want it any longer. He did make the case for the drug but didn't fight me on my decision.
Your neuro is a part of your team-not the manager! You along with your loved ones work together to find the most effective and least harmful treatment.
