Being 183 lbs. (83 kg) and 6 foot (183 cm), how much distilled water a day could i consume before "possible" negative effects start to kick in?

Same as everyone: No matter your weight and height, the body works the same. Your total daily water NEEDS are just about 1500cc of water. With good kidney function, 2-2.5 litres, would be excreted by urination. Beyond that, unless doing strenous work and exercising and sweating a lot, excess water MAY just dilute your blood and cause hyponatremia which is NOT a good thing. Moderation in all things is wise.

Water: You should not be drinking distilled water but water with electrolytes in it. You weigh 83 kg so your maintenance fluids are about 2700 cc/day.
