Welcome Cascadian, you've made a great decision to quit!
This site can be extremely helpful in that experience. You can get some excellent advice, crucial support when you need it and most importantly, accountability to your word.
The backbone of this site is "posting roll." The way that you do that is by finding your quit group. Your's would be February (
topic/30053935/19/#new). It's February because that's when you'll hit 100 days free of nicotine, considered your Hall of Fame date.
Roll is first thing every single day and it represents your promise not to use any nicotine product for that day. So you do it first thing and every single day. It's also a requirement for posting on this site.
After that, you can use this intro as a log or as a place to ask advice. Your February group will be made up of folks in about the same spot as you, so those are the people who will help drag you through the tough times, although you're welcome to explore and post all over this site.
A piece of advice - don't place this quit on your son. It's good to be accountable to your family, but the quit has to be for you and about you. Don't "do it for him" because you'll just end up failing and resenting him and you for that failure. You need to want this and be willing to work for it.
Also, one piece of clarification is needed. You say '"have been here before." Does that mean you've been on day 3 before, or you've been at KTC before, under a different screen name? If it's the latter, you will need to use your original screen name.
Welcome again and reach out if I can help with anything.
