There are these things called hormones in our bodies. These magically little things are activated in various amounts for many things. One special one is actually there to help keep idiots like you alive.
It's called anti-diuretic hormone.
This hormone is released in an inversely proportional manner to the amount of fluid you take it.
So.....if you don't drink water, ADH will make you HOLD water.
