No need to delete the post. The holidays can be a stressful time and it is good to have a lot of information about keeping the quit during them.
It sounds simple but really NOPE is the way to go. Make sure that you realize that nothing is worth blowing a quit over and do whatever you need to keep your quit and never taking another puff.
It may involve avoiding alcohol if you are in stressful situations where drinks are available. I would definitely advise this early on in your quit.
It may involve going into gatherings with relatives that you know you clash with by having the attitude that nothing they will do will lead you to smoking. You will not let them have that control over you.
Families are a beautiful but stressful thing. Most of my family is somewhat normal but there are plenty of clashes and alliances when the whole family gets together.
The one group that really stresses me out is one set of grandparents that are in their early 90's but have always been very manipulate, controlling, and deceitful. I had a big falling out with them a few months into my quit and I thought really hard about lighting up. I decided that I was not going to let them have that type of control over me. In fact, I was so angry with them that I refused to let the have that control over me.
If there are relatives that go out of their way to piss you off, use that anger and stress to strengthen your quit. Promise yourself that you will not let them have that control over you.
Quitting smoking is all about gaining control of your life back anyway.
