If the water that you drank was from the tap, you could have gotten sick from that. Your body might not be used to the purifying system that your house/state use, and if you only drank bottle water (since you stated that you hardly drink water), it could have a negative effect. Also, psychosomatic is also likely. 4 glasses of water isn't enough to really overflow (literally and metaphorically, of course) your system. Hope you feel better!
