I hope you do better with the switch :) You have a good doctor there, looking out for you, and willing to change. Those scientists are learning more, and more about responses to meds. In our near future, they are going to be able to start MSers on meds that they will more than likely respond to based on biomarkers! Until then, trial and error, but at least we have those options! Thanks for being here with us :)
Welcome to our community! I hope you will find the MS group here helpful to you on this journey. -L
