What is warterboarding first of all? It's a method of torture, used by mostly CIA(Central Intelligence Agency).
Method: First, they will take a tank with water(a box at least bigger than public swimming pools). Then, they will ask alot of people to pee of the water to make it toxic enough to torture. Then they put you in it, and make sure that you will not reach the surface. They repeatedly do it until you get what they want.
Side effects: You will have flashback of the torture at every five minutes when you sleep. Your entire body will receive permanent(critical if possible) damage. Your mind will tell you not to take shower, not touch anything that is liquid.
Victims: Terrorist of the al-Qaeda, who were responsible of the attack of 9/11. The genius planner Muhammad was repeatedly torture by about 200 times. Physicians said Muhammad was never the same again. Some said he has gone crazy.
