There’s a huge difference in the amount of water I drink at work versus at home, and I finally figured out why. In my office I have a bright Nalgene bottle that I sip from constantly, and I refill from the water cooler the moment it’s empty. But on weekends, I’m always forgetting which cup is mine, and hours will go by without me having anything to drink. As a result, I get dehydrated, which makes me feel sluggish and can even bring on a dull headache. So I went to the store and bought myself another colorful bottle to store at home. That simple move has done the trick. The new Nalgene is easy to spot on my counter and I don’t confuse it with my husband’s glass. Plus, I bring it with me from room to room, so I’m always reminded to drink up.
