Vegetarians and vegans--what foods (or supplements) do you eat when you feel a bit run down and fatigued?

THANKS!

I grew up eating meat most of my life. I was veggie for 3 years and vegan for more than 5 years. I've been run down and fatigued during all 3 stages of my life. I agree with other posters being run down and fatigued usually is related to other things going on (not enough sleep, too much stress, too much work/ school work). If there are no external factors leading to my fatigue I generally shouldn't have too much problems if I am eating proper vegan meals. However, a trick that has worked well for me is eating a higher protein meal for breakfast. I try to eat my protein-heavy meal in the morning rather than the evening. I find this gives me more energy and makes me feel full for the whole day. Peanut butter is one thing you can try.
