tAN will be delivered at a duty cycle of for 5 minutes ON and 10 seconds OFF for up to 168 hours (7 days) therapy duration. Stimulation intensity will be customized to the participants comfort level and within range of therapeutic effectiveness. Participants will receive 3 placebo pills four times per day for 7 days. The placebo will appear similar to lofexidine in size, shape, color, and smell to lofexidine.
