or you could get the main ingredient (4-AP) from your compounding pharmacist now.
I am using it now, and although its not a magic pill, it certainly makes me feel much less MS'y
From my understanding. fampradine is simply slow release 4-AP; 1 a day maybe?. I just get smaller doses made up, and take them more often (with a "slow release" filler capsule)
Although, I have actually cut back as I have recovered.
