Hitting the bottle
I know I'm supposed to drink lots of water (and now that I'm a nursing mom it's even more important!) but I can never seem to get enough. So to guarantee I guzzle, I've started filling up two 20-ounce water bottles as soon as I get to the office in the morning and then I sip all day long. By 4 p.m., I've usually finished them!
P.S. There are tons of reusable bottles you can buy, but I love the new Camelbak Groove because it has a built-in filter. (It makes tap water taste as good as water from the kitchen's cooler!)
