Hi, I'm interested in any personal experiences from those who have used interferons for MS over a period of 10 or more years. Did you stop them? Did you discover any side effects that developed late in treatment? Have you changed multiple times?

I was on Betaseron for about 5 years and developed severe depression which is very much out of character for me. I then switched to Copaxone and have been on it for almost 6 years. I don't feel it is helping and even wonder if it is making me worse. Please tell about your long-term experience with interferons.
