Study Arms:
- Pregabalin (Type: ACTIVE_COMPARATOR): Subjects randomized to this arm will receive the following dosage:~75 mg (one tablet) twice a day for three days, increasing to 150 mg (2 tablets) twice a day for three days, escalating to 225 mg (three tablets) twice a day, through week 12, day 1. Days 2-4 of week 12, participants will begin tapering and will receive 150 mg (two tablets) two times a day and then days 5-7, participants will receive 75 mg two times a day for the duration of the study.
- Placebo (Type: PLACEBO_COMPARATOR): Subjects randomized to this arm will receive placebo matching the study drug.

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