A method of reducing the viscosity of a water-based drilling fluid without requiring dilution. The method of reducing the viscosity of a water-based drilling fluid, includes: providing a water-based drilling fluid containing a peroxide degradable polymer and a weighting agent, adding a viscosity reducing additive containing an inorganic peroxide to the water-based drilling fluid while maintaining the pH of the water-based drilling fluid at a pH greater than about 8, circulating the water-based drilling fluid having a pH greater than about 8 through a wellbore, and heating the circulating water-based drilling fluid to a temperature of at least about **0° F. so as to activate the inorganic peroxide to degrade the peroxide degradable polymer.
