hello my name is Molly. I have relapsing remitting MS. Diagnosed in 2003. I've tried avonex and rebif with terrible side effects. I had my first infusion of Tysabri on the 22nd. I am looking to get as much information as possible from others who are on Tysabi. No side effects yet. I'm still unsure if I will stay on this drug. I am a little anxious. Maybe hearing other's experiences will help me with my decision. Thanks for reading! Molly
