I've been back on Copaxone and off Tysabri for almost a year and a half and doing great.

I had my bi-annual checkup with the neuro last week and all of my neuro checks were great. He didn't mention anything better than Copaxone so I'm staying with it for now. He did tell me that there are many more cases of PML and he doesn't think Tysabri is safe. I reminded him that I'm doing better on Copaxone than I did on Tysabri. He asked me about my worst symptom and I told him it is definitely fatigue but I'm grateful because things could be much worse.

I don't argue with anyone who is doing well on Tysabri and aware of the risks. If I were in that position I know I'd do the same.
