My legs are really sore today. I was extremely tired around noon, and have had some headaches across the middle of my head, side to side over the top. It's possible that the weather changes have been playing havoc with my sinuses, so I can't really attribute that to the vitamins. My stomach has been a bit queasy, which is likely the fish oil, I think.
Obviously it's too early to see any real effects from any of this.
