Hi Sam,
Well, I'm just not sure. I'll tell you, I went on Rebif not long after being dx'd and I'm off of it now for a short time (for other reasons), and I'm curious to see how I feel after I restart.
For me, I could not tell the difference between MS feeling like ****, or Rebif feeling like ****. I really did not have enough time w/MS to know the difference.
Now that I've had this gap in time, I feel I will know the difference too.
