Welcome, Keri..
Hate is such a strong word.....and, yet, in some instances, not strong enough.
Hang in there and don't take too much IVSM. It doesn't work as well with the 2nd or 3rd + times, for most people.
Good luck with the Tysabri. I hope it works for you. Just be sure to weigh all your options and the benefits & risks before jumpin in.
