I picked Copaxone because I too didn't want to have flu symptoms, I liked the relative portability without worrying too much about refrigeration
, and also the liver issue. However, within several weeks I developed a huge allergic reaction to this. I think the Copaxone people, Shared Solutions, way underplay site reactions to their drug. Nearly everyone here on Copaxone has some site reactions, but mine were just extreme. So I was taken off it.
