Hi, my name is Kathy and I'm new to this site. I was diagnosed with RRMS in 2005 and was on Copaxone until January 2013. My neuro put me on Tecfidera in July. Been on it now for about 6 weeks. Was feeling pretty good until I started the Tecfidera. Now I feel like crap! Read on other posts about changing the diet. Will try that and see if things get better.
