urine drug screens collected in our study 27 (2%) tested positive for other drugs of abuse, primarily marijuana and prescription drugs. Five subjects attended individual therapy and nine attended Alcoholics Anonymous (AA) meetings during the course of the study. Attendance was not associated with drug group or primary outcome measures, with one exception: subjects who were completely abstinent attended fewer AA meetings than those who were not abstinent (41 vs. 89 meetings, p=0.01). All drug-related adverse events resolved within 1-week of drug discontinuation. There was no evidence of rebound in alcohol use, craving, insomnia or dysphoria when gabapentin was tapered.
