I haven't had a Coke since last Monday. That's twelve days now. I'm pretty proud of myself, so I wanted to share that. And I've only had a few Sprites/Sierra Mists. Mostly I've been drinking LifeWater. I only had a headache for about three days, and that was over a week ago.
Actually, come to think of it, I haven't had any caffeine at all. I don't drink tea or coffee, and I have Aleve and caffeinated mints but I haven't had either one. I have had some M&Ms (pumpkin spice, exclusively from Target!) in the past two days, so I guess those probably have a little caffeine, but that's it.
