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; and 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.
