Here, Addaway,

I'll throw out one that will seem counter-intuitive, but maybe you already do this: cut out caffeine. Amen says to do this. He says caffeine limits blood flow to the brain. It's a "stimulant" in that it binds to receptor sites for some sort of hormone or whatever that allows blood vessels to open up, so they stay constricted (which is why caffeine often helps a headache) and then your body, sensing the DECREASED blood flow to the brain, goes into emergency mode, pumping out adrenaline, etc. So it isn't the caffeine that stimulates you so much as your body's reaction to what it does. Fascinating. I do find that, when I have caffeine (I love good coffees and teas), I feel initially up, then I get sleepy. When I have no caffeine, I'm steady as she goes.
