1. A system for providing anti-habituating sleep therapy, the system comprising: a closed loop neuromodulator configured to receive first activity information from a patient, to detect a first sleep disorder event using the first activity information, and to provide, in response to the first sleep disorder event, a first series of stimuli using a set of stimulation parameters; wherein the first series of stimuli includes: a first stimulus configured to not interrupt the first sleep disorder event; and a second stimulus, following the first stimulus, the second stimulus having more energy than the first stimulus and configured to interrupt the first sleep disorder event; wherein the closed loop neuromodulator is configured to detect a habituation event and to adjust an anti-habituation stimulation parameter in response to the detected habituation event; wherein the habituation event includes habituation to the first series of stimuli, and wherein the closed loop neuromodulator is configured to detect the habituation to the first series of stimuli using at least one of: a stimulus energy threshold; a number of stimuli in the first series of stimuli; or a duration of the first sleep disorder event; wherein the closed loop neuromodulator is configured to adjust the anti-habituation stimulation parameter after an energy of the first series of stimuli exceeds the stimulus energy threshold; and wherein the energy of the first series of stimuli includes at least one of: an average energy of the first series of stimuli; a total energy of the first series of stimuli; or an energy of one stimulus of the first series of stimuli.
