Abstract
One example provides a nerve stimulation treatment using electrodes coupled to a user. Examples determine a target charge level and output a series of pulses from the electrodes. For each pulse outputted, examples measure a charge value of the pulse and compare the charge value to the target charge level. If the charge value is greater than the target charge level, examples reduce a strength level of a subsequent outputted pulse. If the charge value is less than the target charge level, examples increase the strength level of a subsequent outputted pulse.
