Excess water is potentially a metabolic burden which promotes edema—a state associated with estrogenic influences— the loss of electrolytes, and the dilution of blood which can resemble a drop in energy and blood sugar. Dehydration is no ideal either, so the point is to drink instinctively according to cravings and thirst instead of mindless adherence to "8 glasses of water a day" as if it were a prescription handed down by Jesus Christ. Worst of all is distilled water, because it is devoid of minerals. Mineral water is better, but orange juice and 0% milk is often even more useful as they provide minerals and energy simultaneously. The ideal is to always supply just enough electrolytes—often with some bias towards magnesium—with every drink and meal to maintain a balanced state of hydration that rarely encounters cramps.
Besides fruit juice and milk, other significant sources of major minerals include strong coffee or espresso, chocolate or cocoa powder, fruits, and leafy greens. Dates are surprisingly good for potassium and magnesium. Meat can provide some magnesium but also a lot of phosphorus, so a varied diet is important for mineral balance. Salt helps retain magnesium and prevents cramping, and you will most likely crave sodium when your body needs some, so use the amount that makes food taste good. Magnesium deficiencies are common enough for most people to benefit from its supplementation. Too much calcium from milk can be balanced somewhat by mixing with coffee or cocoa powder.
I drink very little actual water, but I notice I need more when activity levels are higher or sweating has increased.
