They’re both addictions that require you to have strength of mind to combat. Drinking could be occasional and harder to trace than smoking habits as with smoking you are out. With drinking, it could be at night, or on particular time.
Drinking and smoking usually goes hand in hand. There are trigger points for many as when they drink, they usually smoke.
Both of these habits create a void when you quit, and although cravings may vary, it usually is the same—addictive response. Exercising, removing yourself from the situation, cold turkey with plans, and cleansing the mind of addictive behavior with anchor technique are some of the ideas you can apply. It all comes down to mentality and habits. Learning how to create a space between thoughts and triggers helps you understand how addiction works on your body. Meditation is a perfect tool to identify that. Once you create an association for these anchor points, it becomes easy for any habits, as mentioned in the book. Preparation steps are similar for both addictions. It would help if you still prepared for cravings, withdrawal, triggers e.t.c
I firmly believe that dealing with addiction at the root level of the mind is the best way to go. I did this, and I never think about smoking, no matter what situation I am in. I used to be a heavy smoker and, well, a heavy drinker. My cleansing steps helped me get rid of all the bad habits.
