i havn't read everyone's responses to you but wanted to add that i've been on copaxone for 5 yrs without any SE's. i tolerate it well. and while i've technically progressed to SPMS my condition is stable as have been my mri's.
i have c-spine and brain lesions and had a + LP with 2 OGB.

i know that each of us has to make an individual decisions about meds and a lot of folks don't take any.
my personal feeling is that since MS is a non-curable, progressive & disabling disease i'd rather not wait for a relapse to tx. who knows how'd i even be without it. maybe that's just my disease course.

i chose C initially because i was working FT and was single. i didn't want to have the flu like SE's. i also had a hx of depression and didn't want to chance taking the interferons.

so i chose to take daily shots and have no SE's.
i'm sure you're going to be so knowledgeable by the time you're ready to make the decision, yes or no.

whatever you decide will be best for you. and, you can always change course down the road.
