Hi, ! First, please keep in mind that I am no expert and your doctor will know about your medical history than I will. That said, I tend to agree with the other community members that have commented on your post. Especially as lifespan increases, I don't see the correlation between stopping treatment when a person reaches some predetermined age. I am aware that DMTs can have a host of side effects that can have long term implications, but again, I also think starting or stopping any treatment based on one factor seems a bit shortsighted.
But, how have you been feeling since you have been off your meds? Also, has your MS progressed noticeably in this time? I think those two questions are very important in this discussion.
