Optivite P.M.T. side effects

I find the above woman's comment very strange and out of the ordinary. I wonder if perhaps there is something in her diet that is causing such an adverse reaction. Vitamin B's, in high quantities, are exactly what women need. As a pregnant woman, it is B6 that reduces and even eliminates my morning sickness. The proper balance of vitamins and minerals in Optivite ensure the proper ingestion of the B6. Love these vitamins!

I've tried taking just one pill as a daily vitamin supplement, and I found that I makes my mood drastically WORSE. I can go from calm and content to miserable and tearful instantly, and for little reason. I've done a bit of research on B complex vitamins, and think this might have something to do with it. The B complex amounts are ridiculously high. This can't be good or me!
