My prenatal is chock-full of vitamin B and I do feel better after taking it - I also drink 8 oz of OJ and eat a banana and a boiled egg (can't do the yolk though, ugh). I find that getting the protein helps a lot - I snack on raw almonds throughout the day also. The banana and OJ have potassium, vitamin c, calcium, and folate which are all important too. It's the only combo I've found to get me off to work in the mornings without feeling cruddy.
