I'm not drinking enough water

I've just realized that I've gone over a week without hitting my water goals. I should be getting at least 64 ounces every day. I been drinking about 20oz. at work then on nights I was getting another 20oz or so. (I used to do two 20oz bottles at work.) But I haven't been drinking like I should be when I'm at home in the evenings. Need to work on that. ~Pam
