Abstract
The cranial electrostimulation devices described herein are suitable for use in detoxification from and amelioration of the symptoms of acute and chronic withdrawal from simultaneous multiple addictive substances by transcutaneous electric nerve stimulation. A plurality of time-division multiplexed analog waveforms is applied to the mastoid process of a person in need thereof, thereby treating symptoms of withdrawal from addictive substances. The invention also provides a protocol for encoding a plurality of different waveforms combined sequentially or simultaneously, as well as an improved cranial electrostimulation apparatus having a stable output waveform signal over the useful service life of the power supply, e.g., the battery.
