Unlikely: Depending on how many ks you weigh, drinking that much water shouldn't cause you any problems. A normal 70kg individual requires about 1600mL of fluid replenishment by natural losses daily. For heat, sweat, or other losses you would increase accordingly. For every 1 degree above 98 degrees Fahrenheit your daily fluid requirement increases by 125mL/day as well. Many gallons will cause trouble.

Unlikely: It could if you did it daily for weeks. That can cause psychogenic polydypsia and is seen in psychiatric illnesses. There has been documentation of water intoxication acutely, but this take many gallons of water. A woman I believe Nevada drank 40 gallons in one day to cleanse herself and she became intoxicated with water and died.. Water intox causes low sodium levels.
