Good luck, seeker and fayerody and all others trying to quit the caffeine habit. It usually takes me 3 days when I wean off caffeine, before I am headache-free and back to my usual mood (not so cranky). Hang in there, it shouldn't be long. I have weaned a number of times in my life, and usually do it by going cold turkey. Right now I am at a stage where I don't drink coffee, caffeinated pop, or black tea. But I drink 1-3 cups of green tea a day. This amount works really well for me and my health, plus I get all the good cancer-fighting stuff in the green tea.
