Additional Study Information: NOTE: YOU MUST HAVE HIV AND HAVE EVER HAD HEPATITIS C TO BE ELIGIBLE FOR THIS STUDY!! ............... For individuals who have both HIV and Hepatitis C virus (HCV), heavy drinking poses serious risks to their health. We do not yet know which interventions are effective at helping individuals with HIV and HCV drink less. The goal of the study is to compare two different interventions to find out if they help patients drink less. Patients who are eligible will be randomized to one of two conditions. One group will receive in-person meetings with a counselor and will use a smartphone app to track their drinking over two months. The other group will receive educational materials and advice to decrease drinking. Participants will complete five appointments (a screening, three study appointments with a counselor, and a follow-up survey) over three months. Participants will be compensated up to $280 for full participation in the study.
