Welcome to EX you have come to the right place to work on protecting your quit. I believe what you are feeling is rather normal You may have become to believe the Chantix was the cure, but it wasn't. It was your willingness to do what ever else was necessary not to smoke. The Chantix was just an aide to get you there. You still had to not smoke. So never give up on what you have achieved or lessen where you are so far, never go back to day one. Here we have a NOPE concept which basically boils down to no matter what is happening in your life not to smoke because life is going to happen.
You say you have changed your habits. You also have to change the way that you think. Start believing you can stay free. Realize that you do not have to smoke. Take the option to smoke off the table completely and have other things in place when the urge should come. See the blog @101 Things to do Instead of smoke.
Yes, there will still be instances that your old smoking brain tells you that you want a cig. Just because you think of something does not mean you have to act on it. Those thoughts subside that you can just swat them like a gnat. Stay around and develop more tools and skillsets to remain free. Congratulations on 6 months of freedom.
You've done that yourself! Chantix gave you the courage to begin.
