Complacency

This is my third attempt to finally quit smoking for good. I am surrounded by a husband and two adult children who smoke. First time I gave up for two years (cold turkey) and second time for (4months). Started again as I was complacent! Had one or two drags whilst I had been drinking and thought "how easy is this"!!!! Now I find I am smoking more than I ever did. My first smoke during the weekday is when I get home after work. I need to stick to my goal this time. History of cancer in the family etc. This is the first day. I am at work and yet to go home but am determined to quit for good this time. I will not fall into the old "complacency, I can do this trap" again!!!!!!!!!!!!
