Lethargy during the day is a large problem for me. If I do not consume a chemical (such as caffeine) I have difficulty functioning to my fullest potential. However, if I do consume caffeine--even a tiny amount, such as half a cup of coffee--I go stir crazy for an hour or so and cannot concentrate very well. Also, if I drink caffeine less than 14 hours before I want to go to sleep, I have a hard time falling asleep. Is there another substance I can take besides caffeine that will give me some pep without as harsh side of effects as caffeine?
