First of all.........welcome, Sam! How old are you?

Your MS is probably relapsing/remitting MS. That means your body has an attack and then kinda heals itself. The attacks can come often or far apart.
The drugs are thought to slow down the rate of attacks and therefore slow any progression.

I would seriously have a talk with your doc about the meds, because the early part of the disease is when they work!
I was diagnosed in 2002 and had off and on symptoms since 1989. None of my symptoms ever led me to believe I had MS! Your well meaning friends "know" MS in its worst light. Forget that stuff. MS can be mild or it can be really nasty. No one knows why it hits some people so hard and others not so much.
I am fine and so is my brother in law (a prominate Judge) and he was diagnosed 10 years before me! Before MRI, the docs wouldn't know what was wrong with people like me because we did not fit the obvious profile.
