Do any of you get B12 shots? My freind at a DI school was talking about how thier team gets them to keep them healthy, and I always get sick in the winter with colds, and was wonedering if they help. I always eat healthy, take vitamins, but no matter what I still get sick each winter and destory my base. Also, if anybody know if they help, and of any other vitamins to keep healty. And, if you know how much they cost (if not covered by insurance) Thanks. DIII
