The purpose of this research is to understand the relationship between these three factors, which will help improve medical treatment and overall care for substance misuse in the future. Participants will be randomized into CBTi and sleep education groups, and their substance/ alcohol use, sleep parameters and reward sensitivity will be measured at multiple time points.
