Rethinking Drinking and Beyond Hangovers are two great resources from NIAAA to use with patients or clients that can help them sort through their use of alcohol. 


A Guide to Low Risk Drinking. Developed by the US Department of Health and Human Services in collaboration with the IRETA.


Agency for Healthcare Research and Quality's (AHRQ) guide on Medicines to Treat Alcohol Use Disorder: A Review of the Research for Adults. This guide could be used to talk with patients about their alcohol use disorder and treatment options that are available.
