A great book for those of us with mental illness

In my home town I started a dual diagnosis group (for this with substance abuse and mental illness) and I wanted it to be based on DBT (Dialectical Behavioral Therapy) as I think its unique and can offer help in ways AA cannot. To start this program I spent a manic winter reading DBT books. I've found this book to be the most approachable and after almost a year of running the program I've found other agree. Good luck and good skill, I will not drink with you today. Remember to take your meds
