Aww, don't freak out. You'll do fine. You know and understand the one day at a time.
The days immediately preceding my quit day were the worst, IMO, since I started the whole plan/pill/regiment. I was okay in the very beginning, okay once I quit, but I'd say about the three days before and after my quit day, I was a wreck.
Just keep thinking of all the reasons why you want to quit. You will notice improvements very quickly. Remember all those dollars you're saving, and treat yourself to something nice -- often
Plus, it's just so hard to be a smoker anymore, you know? You really can't smoke in too many places nowadays. And even if you do, I'm sure you get the same looks of disgust and coughs from passersby as I did. It's just too darn hard to smoke anymore!
I hope the Chantix works as well for you as it seems to be doing for me. This is the first quit in my life where, ten days into being smoke free, I really feel confident I can do this. All of my other attempts, geez, if I even got to a day ten, I was so depressed and just out of control. Keep an eye out for side effects. It did not agree at all with my hubby.
You can do it!
