Aggressive route?

In 4 days I’ll be meeting with my ms specialist neuro regarding my new reality and regarding treatment options. So far she’s said that she recommends the aggressive approach which I’m assuming are the infusions. Can anyone share what this is like? I don’t want to rush but I do want to do my best to take the best care I can of myself.
I’m very disciplined already / pre diagnosis with diet. But, what are thoughts? I do see some side affects that appear alarming…any advice, comments, direction, will be and are much appreciated
