I fill empty an empty water bottle from the water cooler at work (technically a 5 gallon bottle I guess, so I counted that as 2 bottles) and from my Brita pitcher at home (counted that as non-bottled). I usually have two bottles at home I rotate through and toss them after a couple weeks. I go through 6+ 16oz refills a day now. Up until October or November last year I was probably drinking that volume in Diet Coke! Now it's just diet coke with lunch, and sometimes a can at dinner.
