Bottled water is bad for the environment, so consider a reusable metal bottle from SIGG (www.mysigg.com). These bottles come in a variety of colors and patterns and will save you from having to buy bottled water every week! Instead of using those flimsy plastic cups, you can bring your SIGG to the office and fill 'er up using the water cooler.
Tip: You can flavor tasteless water with slivers of cucumber (for spa water) or with an Emergen-C vitamin packet powder for a boost of B and C vitamins and immune-boosting zinc.
