Hi Keith..
I totally understand what you've been going thru, as I went thru the same on Rebif for nearly a year. When I couldn't take anymore, and realized the medication was making me feel worse than the illness it was supposedly helping, my neuro had me stop taking it. I, too, felt almost instantly better. He put me on Copaxone, and I never had a bad reaction to it. The Rebif was definately working, because the follow-up MRI I had before quiting showed improvement in the old and nothing new, but I felt like a zombie..a sick zombie..I hope you find something that works well for you!
