"I had been on a couple of medicatios, the best of which for me was Copaxone.  In fact, I had relatively few symptoms and it wasn't really visible.  Then I started Gilenya because it was supposed to be so much better, and oral, to boot.  I have lost so much function in terms of walking and balance in the last two years.  I went back to Copaxone but am afraid that I will never regain what I lost"
