When I was first dx'ed with MS, I used Rebif. All the DMD's are fine, it just depends on you and your doctor and the people here who love their way of treating the disease.
I only used Rebif. I had NO side effects from it. With the auto inject, it was more a mental thing than a pain from the shot. Just a minor sting of being pricked.
PM me if you want more on Rebif. I will be happy to tell you my details, etc rather than post them on this thread.
PS - sorry to hear you have MS.
