A method of servicing a wellbore in a subterranean formation comprising placing a wellbore servicing fluid in the wellbore and/or subterranean formation, wherein the wellbore servicing fluid comprises a viscosifying polymeric material, a breaking agent comprising an inorganic peroxide of a divalent metal M(II) characterized by the general formula MO2, and a break rate controlling additive comprising a M(II) soluble salt, a M(II) precipitating salt, a M(II) surface precipitating salt, a M(II) solution precipitating salt, or combinations thereof, allowing the wellbore servicing fluid to break, and flowing back to the surface at least a portion of the broken wellbore servicing fluid.
