This is something I heard about some time ago. I've never done the 8 glasses of water thing - in fact when I get to about 4 glasses over a day I start to get quite light headed and don't feel good. There are occasions when I can and do drink a little more, but they are very rare.

I also eat a *lot* of fresh fruit so would be getting the bulk of my water from that.
