You will read people praising and hating virtually every drug on this site!
I am on Avonex, the first 2-3 shots gave me minor flu symptoms and now I have no reaction. I like it because it's once a week and interferes with my life very little. I am staying pretty level in my symptoms; some balance problems, fatigue and loss of hearing are stabilized.
I have a friend who has been on it 5 years and has had no recurrences. He's my hero!!
