I took Rebif for a little over 3 years then stopped last year while I was being treated for breast cancer (surgery/chemo). I've hit the medical jackpot, haven't I? Well I am doing well now and will be re-starting Rebif next week. Do you have any advice for me? I am particularly interested in what you might have to say about pre-medication and post-medication. Thanks for your help. I look forward to hearing from you. IRENE
