Most studies I read on caffeine are either inconclusive or they contradict other studies done on the subject. So there is basically only one good way to find if caffeine works for you. Try it. But do it scientifically an be strict about it. Try different drinking patterns and amounts during different weeks. Write down your experiences. This is important. From my personal experience it helps me to stabilize my wake and sleep cycle. I am more awake during the day and get more tired at night, which is a good thing. I might add that I only dring 2 cups daily and I never drink coffee after 3:00 pm.
