According to an embodiment of a method performed by an implantable medical device to deliver a neural stimulation therapy to a patient, a lower dose of the neural stimulation therapy is delivered to the patient. The dose of the neural stimulation therapy is automatically increased from the lower dose to a higher dose, and the higher dose of the neural stimulation therapy is delivered to the patient. A trigger that is controlled by the patient is detected, and the dose of the neural stimulation therapy is automatically returned from the higher dose back to the lower dose in response to detecting the trigger.
