Personally, I do not measure the amount of water that I drink everyday. But, I drink a lot after I urinate. To think that I urinate, 5- 6 times a day so I think I consume the right amount of water each day. Sometimes I do not drink a lot of water when I am not at home or work like if I have to go out like a place that I have to find a rest room. I'd rather endure being thirsty than being wanting to find a powder room.
