Hi Niki,
I was on Rebif for about 3 months. I had a lot of the side effects they talk about but they took me off because my liver enzymes went up. I am getting ready to start Copaxone in the next couple of weeks. The side effects can be kept under control with tylenol and advil, I am just super sensitive to all meds. I have a client that is on rebif and she has no problems with it at all. I think everyone is so different. Good luck. MS lifeline which is rebifs nurses line was wonderful. You will get any question answered there. Let us know how it goes.
Cindy
