I used to feel tired all of the time and drink coffee to try and boost my energy level. Of course we all know that caffeine is a drug and it will raise energy artificially for a short time before crashing your energy levels down lower than before. I made a new years resolution to be healthier and as part of that program my food intake has been more focused on fresh fruits and vegetables to help give my body the nutrition it was lacking. I gave up my mid afternoon coffee and changed to juice drinks to get vitamins and natural energy boosts instead of caffeine.
