They will be randomized according to a predetermined random order to vitamin regime or Centrum forte. Doses of risperidone will be lowered as clinically possible. Risperidone dose will be recorded weekly and will serve as a secondary outcome measure. A registered dietician will meet with each patient weekly and discourage refined sugar or excess fat and encourage regular fruit and vegetable consumption. High protein breakfast will be emphasized. Fifteen patients will be started yearly for three years.
