There is a thing line between what is sufficient and what would be too much. Drinking too much could possibly deplete your electrolytes. If it was me I would not drink more than one gallon a day.
As it is for me it is not possible or practical to drink half my bodyweight in ounce aaand drink the lemonde. I would hafta live 10 ft from a bathroom. I do equal water to lemonades and even with that if I hafta drive somewhere I bring a big empty bottle with me in the car in case I get stuck in traffic ;+D
