I take a multi-vitamin when I remember or when my bowels will take 'em easily. I usually take the One a Day Active that has Ginseng, which does seem to help give me pep and it's an antioxidant. I tend to take some of the herbal energizers like Ginseng, guarana, and the like. I've got little vials of Chinese Ginseng and royal jelly that I take when I'm really dragged out. I still try to take vitamins even when I can't take the big multi-vitamins by buying some Flintstone's chewables. You don't have to worry about them getting stuck because they didn't digest all the way.
