Hey Cindy Lou Who! I recently quit taking my Rebif because even on it I too went downhill and was diagnosed SP. I am currently fixing to give Tysabri a go and see how that works for me. I too have wondered about the long term issue as it doesn't seem like I can make it thru the "short term!!"

For those who questioned the length of time on The chemo drugs...the simple reason for that is it will chew your heart valves to smithereens if you stay on it more than the recommended doses!

back to Cindy...what are your side effects on the Copax? Doc had mentioned that to me as well if the tysabri wasn't good for me.
