My mininum daily water intake is 48 ounces...yesterday I had about 100!!! I have a 20 ounce water bottle that I use - my goal is to drink it in the morning, refill it and drink another during work, refill it and drink the 3rd on the way home. That is 60 ounces so I meet my target of 48 ounces. Yesterday, though I drank four refills which is 80 ounces then Michael and I went to dinner and I had about three glasses of water there!! I can't believe I wasn't up all night going to the bathroom!!!
