You're more likely to stop drinking and smoking if you seek support from those around you.  Ask them to support you by not drinking and smoking around you. If you have other friends who are looking to quit drinking and smoking too, make a pact for healthier choices. Check in with each other daily and hold each other accountable for your choices. Reach out to smoke-free groups, such as smoke-free Alcoholics Anonymous and other support groups, like Nicotine Anonymous. Talking about your efforts in a supportive environment with people who share similar experiences can make all the difference in your attempts to quit. If you are concerned about living with people who may trigger your alcohol or nicotine use, consider finding a sober house that bans alcohol and nicotine. All individuals living in a sober house agree to live sober and create an accountable community for each other.
