Hugs and sorry you have to go back on the C . I am new to taking C but so far am having a hard time with it and they wanted me to do Ty but I couldn't bring myself to it. I am trying my best to deal with these side effects as C doesn't cause liver damage but Rebif was causing me liver problems. I know that I can't wait for a day where they find a cure. Hugs and at least you get lots of icecream.
