whoever told you that is an idiot.
Which is not surprising because a lot of "diet gurus" and their followers are idiots
1 gallon (128oz) is the optimum reccomended intake of water for someone 120-130lbs. Especially if you are eating lots of protein- which many diets reccomend.
btw- if you gained weight it was not from drinking water. Drinking water, especially cold water RAISES your metabolism. (your body expends energy to raise your core temp which drinking cold water lowers (slightly))
it is true that you can drink too much water, though its quite difficult and you will feel very ill prior to it becoming an issue.
