Welcome Chris and congrats on your decision! You've come to the right place if you're ready to quit.
You're correct that it won't be easy, but everyone here is a testament that it can be done successfully.
This site is a great resource for information and motivation, but it's most powerful tool is accountability. Check out the Quit Groups page and find yours (November Pre-Hall of Fame 2017). Groups are set up based on Quit dates and what month you'll reach 100 days (considered Hall of Fame). You "Post Roll" with your group every single day, as soon as you are reasonably able. That post is considered your promise to not use any nicotine products for that day. Instructions on how to do that are in the Quit groups.
The principle is that anyone can manage to go one day without using. Don't worry about forever because that's too big. Just focus on keeping your word for today and tackle tomorrow when it gets here.
Your group will be comprised of people with similar Quit days, so you'll all be going through it together. It's a great resource for support, accountability and even a good place to blow off steam, because we all get it.
Welcome again and please reach out if I can help.
