I find caffeine really doesn't help all that much although I do generally drink a partial cup of coffee or a diet soda sometime in the morning. Too much and I get strung out and too wired to work efficiently. And.... it makes me tired not long afterwords. A little tiny bit in one or two doses a day isn't bad but much more and it becomes counterproductive. My favorite drugs? A good light meal, fresh air and a nice long walk in the sunshine.
