Eliza I have one of those office water cooler bubbler things here at home. The doc told my missus she needed to drink lots of water when she did the chemo. You know I actually save money compared to the brita thing that use to clog up all the time or the water bottles. What is great is the cooler thing gives you both cold and hot water. I get the big bottles delivered. Our water here is from Lake Erie (no thanks) I will drink the bubbler thing. They guarantee it is pure.
