Change: drink 16 oz of water a day

I thought I would be pretty specific about my changes, especially this first one. I want something I can measure, so that I can know I'm being successful. I know that 16 ounces of water isn't a lot. I know that in the past I've consumed almost a gallon of water a day. I've recently realized that some days, all the water I consume is when I'm brushing my teeth. That's not good! If I drink more, great! It's a start. And I'm starting today! Even though it's 10 pm and it means that I'll probably be up all night using the bathroom, I will drink 16 ounces of water before I go to bed.
