Ok, I weigh 105 and I know that your suppossed to drink half their weight in water per day .. I mean then it would be 52.5 oz drink, but before dinner I drank a lot and I have more than three drinks in the evening .. Is this bad? Am I drunk?

a good rule of thumb is 8-10 glasses of water a day. nothing more than something good for less than 10 liters and will not do any damage to your body anything above this will not cause much damage, you should not really be a problem on the water, the better.
