Drinking water Before sleeping is really preventing the Heart attack happens in the Morning , but we must maintain drinking plenty of Water each day even if this will bring us Pissing constantly .
But also try Drinking warm Water each time to help slowing the building of cholesterol.

The most important thing in our world. I drink at least 3 letters per day. And if you think about it everything in our life depends on water so everybody knows how important is it ! Somebody once said '' The water is life ''
