Welcome back Rollingstone! Here's to tomorrow!
Here is how my quit is going: I'm still at it, and now the days count is going by faster than during the first week. Be frank with yourself - there will be some times when you feel like packing it in - but they do pass! Believe that and keep up the fight. Call your friends, post here for support, keep busy, do anything but give in.
The first week is hard. Keep the positive goals and rewards uppermost in your mind. During the first week my self-image was one of a struggling ex-smoker. I found it daunting to commit to never smoking ever again, so during the first week I committed to myself to just last the one week.
Now in the second week my self-image is evolving into a more rewarding non-smoker image. Big difference, at least in my mind. The second week is easier, but there are still temptations even though they are shorter lived and less frequent. It's like losing weight - once you see some progress, your motivation increases to keep on keeping on.
Maybe everyone fears failure. Failure feels terrible. The daily messages have been very supportive - if you do slide, take the opportunity to learn why, and then move on. A failure is not the end, it is a step along the road and an opportunity to strengthen your resolve.
You can do it buddy! Won day at a time.
