I had started feeling really good after having a cold for 2 weeks. I had not taken my Rebif for 2 weeks and whenI started feeling well again, I started back on my MS therapy. The 1st shot I was okay. Today I feel horrible. My hands are numb and I can hardly concentrate. I am going to bed. Didn't get up until 10:00 a.m. as it was. I feel lazy but I don't care. I need sleep!
