Why do u crave ciggerettes when u drink?

Guilt by association. Many people combine smoking and drinking - and it becomes a very compelling habit. One substance becomes a trigger for the other. One thing that helps in stopping smoking is to avoid situations where you are drawn to drink alcohol. Read alan carr's book on smoking cessation, and ann fletcher's excellent book, "sober for good." stop both of these habits and you get to live longer. Good luck.
