First of all, you have NO reason to beat yourself up like this hun! I'm sure there are MANY of us here that have cheated (tho I haven't reached my quit date yet, I started the Chantix 3 days ago and was "supposed" to be down to 1/2 pack by now). The best thing you can do for yourself is to FORGIVE yourself and pick right back up where you left off! If you can't stop completely right now, maybe try cutting down, smoking half a cig instead of a whole one. Just remind yourself that if you cut ONE smoke a day every day, you could still be quit by the end of the month...that's not so bad considering how long you've been a smoker, eh?
Just remember that what you are trying to do is nothing less than heroic...beating any addiction is hard but with an addiction to something that's legal, and has so many people everywhere you go literally blowing smoke in your face remind you of your addiction, it's tenfold! You've gotta be kind to yourself and give yourself a break. With the desire you appear to have, it's apparent to me that not only do you WANT to quit, but I believe your determination will win and you WILL quit! You can't expect it to happen overnight. Maybe some people can throw them out and never smoke again, but people like you and I can't do that.
Don't give up....keep working to cut back, distance the time in between your smokes, etc. Also, I'm new here so forgive me if you've posted this, but are you using anything to help you quit like the patches, Chantix, gum, etc?
Best of luck to ya...God Bless you!
