Remicade

I am 49 years old, and have been dignoised w/RA. It runs in my family. Mother, and two sisters have it. It swist the fingers and toes, and affects the knees , ankles, and lower back. My Doc had me on Predizone, and Methotrexate, but tha did not seem to help. All I did was put on tons of weight. Then he had me on Remicade. that did well for a while, but when after my infusion, I am very tried and have zero energy. I got real sick over Christmas Holiday w/signitis [nose] and bronctis. So my Doc took me off it. Now he wants me to start taking it again. I am not sure what to do. I have to work, [I work for Medtronics] and tend to miss due to the triedness. Is there something else I should be doing???
Any help would be greatly apprecitaed.
