Hey Dana,
Wow, I am sorry!! You have had a really bad time! Hang in there. I don't have any advice I just wanted to offer my support. I am really hoping the tysabri works for you. I too, have heard great things about it. It is supposed to be very effective. You're remaining quite positive despite your tough year. You are very inspiring.
Good luck and please keep posting. I would like to know how you are doing.
Love and prayers,
