How much is enough?

I've always wondered how much water do we drink every day. When I was working,I made sure there's a filled 1.5litre of water bottle in my car and then I found out 1.5litre a day is not enough. So I have an extra 1litre bottle in my car.

And yet sometimes I feel dehydrated, I have cracked lips at times.

So how much of water is enough? You may want to find out more here: http://www.mayoclinic.com/health/water/NU00283

So for a female who didn't do any workout and is not ill or breast feeding, you'll need to empty this many 600ml bottles of water..a day. :)
