NOT EFFECTIVE: If you suffer excess sleepiness (hyper somnolence), you possess a sleep disorder. This is not a problem which will respond to vitamins, but caffeine in coffee or Coca Cola might transiently help. Best approach is too uncover why you have a sleep issue, and get it corrected. Your doctor should be able to assist.
