If I drink four glasses of water in the same day, I spend most of it in the loo.
One glass first thing, yes. One last thing, okay. One in between if it’s really hot, but . . . more? I haven’t got that long to live!
On the occasions when I have tried to “do the healthy thing” and drink four or more, I can only last a few days before I am too exhausted to move. Drinking huge quantities of water literally washes away all your energy, and I don’t believe it’s good for most of us.
