Study Arms:
- Experimental (Type: EXPERIMENTAL): Active TVS will be performed by use of a Tragus stimulator device with electrodes attached to the tragus of the ear. Stimulator will be applied continuously for 1 hour daily for 4 weeks.
- CONTROL (Type: SHAM_COMPARATOR): Sham TVS will be performed by use of a Tragus stimulator device with electrodes attached to the ear lobule. Stimulator will be applied continuously for 1 hour daily for 4weeks.

Based on this trial design, predict the completion outcome and termination type (if applicable).
