I drink upwards of 120oz a day... sometimes more. I usually have a mug of tea with my vitamins in the morning, and then I have 4 or 5 20oz bottles of water at work, with the last one coming home with me... At home, I usually finish that one off, and I'll have one more if I'm going to Zumba, and if I'm not, I'll likely have a 12oz can of cherry coke zero. So... maybe 140oz, LOL. And I'm still here... going on 2 years drinking that much every day, and even sometimes more.
