Hi AMN.
I was only on Avonex for less than a year, but all the effects I had were bad..

I presume you are asking about bad effects, but maybe not?
How long have you been on your particular poison and what good effects have you had?
I'm really wondering if any of the ABCRs are really helping at all. It seems that they only work for people with early onset RRMS and not people who are further along, like me (SPMS now). And we all know that early RRMS heals itself and nerves re-mylinate..right...so maybe it's just the natural way of RRMS and not the meds at all.
For instance, I was in a 17yr remission between my 1st and 2nd exacerbation, without Meds.(they didn't have any back in the dark ages).
So, anyway that's my feeble thoughts and I realize that I really didn't answer your questrion..
