Summarize:

It's hard to beat addiction on your own, and a therapist can be a consistent source of accountability and support. Working with a therapist can include discussing emotional triggers, finding coping strategies, preventing relapse, and digging deeper to understand the emotional causes of addiction.  Staying consistent with therapy is important, especially for addressing relapse prevention.  Addiction can coexist or contribute to psychiatric disorders such as schizophrenia, depression, anxiety, or bipolar disorder. Together with therapy, prescription medications may treat concurrent psychiatric disorders that contribute to addiction. A medical evaluation can help pinpoint how cigarettes and alcohol have affected your body. Work with a medical professional to help improve your bodily health. They can also offer prescription medication to lower nicotine dependence. Both alcohol and nicotine can seriously harm your body. Be honest with your medical doctor and request tests to assess the health of your liver, heart, kidneys, and lungs. If you fear you cannot quit on your own, consider a recovery facility. An intensive treatment facility can help you address the physical and emotional challenges of addiction and quitting in a supervised and supportive setting. A program can help you decide how to detox and will monitor your physical and emotional state as you come down from alcohol and nicotine. Treatment programs include intense medical and psychological supervision.  Treatment often includes intense individual and group therapy that targets mental health conditions. Medication may be prescribed to treat and monitor psychiatric disorders while in treatment.
